Lower layers (MMC / SDHCI controller drivers) may make certain decisions

Assorted fixes to MSI-X/MSI/INTx setup in iflib(9):
- In iflib_msix_init(), VMMs with broken MSI-X activation are trying
to be worked around by manually enabling PCIM_MSIXCTRL_MSIX_ENABLE
before calling pci_alloc_msix(9). Apart from constituting a layering
violation, this has the problem of leaving PCIM_MSIXCTRL_MSIX_ENABLE
enabled when falling back to MSI or INTx when e. g. MSI-X is black-
listed and initially also when disabled via hw.pci.enable_msix. The
later in turn was incorrectly worked around in r325166.
Since r310806, pci(4) itself has code to deal with broken MSI-X
handling of VMMs, so all of these workarounds in iflib(9) can go,
fixing non-working interrupts when falling back to MSI/INTx. In
any case, possibly further adjustments to broken MSI-X activation
of VMMs like enabling r310806 by default in VM environments need to
be placed into pci(4), not iflib(9). [1]
- Also remove the pci_enable_busmaster(9) call from iflib_msix_init(),
which is already more properly invoked from iflib_device_attach().
- When falling back to MSI/INTx, release the MSI-X BAR resource again.
- When falling back to INTx, ensure scctx->isc_vectors is set to 1 and
not to something higher from a device with more than one MSI message
supported.
- Make the nearby ring_state(s) stuff (static) const.

Fix NFSv4.1 client side handling of "soft,retrans=2" mounts.
Normally "soft,retrans=2" cannot be safely used on NFSv4 mounts, since
the RPC can fail and leave the open/lock state in an undefined state.
Doing I/O on a pNFS DS is an exception to this, since no open/lock state
is maintained on the DS server.
It is useful to do "soft,retrans=2" connections to a DS when it is mirrored,
so that the client can detect failure of the DS. As such, mounts from the MDS
to the DSs should use these mount options when mirroring is enabled.
However, the NFSv4.1 client still leaves the session in an undefined state
when this happens.
This patch fixes the problem by setting the session defunct, so it will
no longer be used.
The patch also sets "retries=2" on the connections done by the client to
a DS, which is the internal equivalent of "soft,retrans=2".
The client does not know if the server implements mirroring at connection
time, but always doing this should be safe, since it will fall back on doing
I/O via the MDS as a proxy when there is a failure doing an I/O RPC to the DS.
This patch should not affect non-pNFS client mounts.
