Deprecate the 'devclass' argument from *DRIVER_MODULE() macros.
This argument is useless for the vast majority of drivers. For now,
use __VA_ARGS__ wrapper macros so that that the *DRIVER_MODULE()
macros accept both the old version (with a devclass) and the new
version (which omits the argument and stores NULL in the
driver_module_data structure). This provides an API compatiblity
shim that can be merged to older stable branches.
Once all drivers relevant to 14.0 (both in and out of tree) have been
updated, the API compat shims can be dropped.

nfscl: Acquire a refcount on "cred" for mirrored pNFS RPCs
When the NFSv4.1/4.2 client is doing a pnfs mount to
mirrored DS(s), asynchronous threads are used to do the
RPCs against the DS(s) concurrently. If a DS is slow
to reply, it is possible for the "cred" to be free'd
before the asynchronous thread is done with it, causing
a panic/crash.
This patch fixes the problem by acquiring a refcount on
the "cred" while it is being used by the asynchronous thread
for a DS RPC. This bug was found during a recent IETF
NFSv4 testing event.
This bug only affects "pnfs" mounts to mirrored pNFS
servers.

pci_parse_legacy_config splits the options string by comma characters.
strchr returns a pointer to the first occurence of a character. In that
case, it's a comma. So, pci_parse_legacy_config will stop at the first
character and creates a new config node with a name of NULL.
It simplifies the declaration of the driver structures a little. There
are no current consumers of this macro, in fact it looks like it was
added for exactly this purpose.
This decreases the scope of some variables, so rework the initialization
