Fix an issue with 11g beacon frames which looks to be a limitation
on the largest multi-write size.
From the submitter:
==
I looked further into the magic 88-byte threshold after which the bug
occurs. It turns out that figure included the 24-byte tx_desc, and up
to 64 bytes of beacon frame (header+data).
rum_write_multi doesn't seem happy with writing >64 bytes at a time to
the MAC register. If I break it up into separate calls (e.g. bytes
0-63, then bytes 64-65, written at the appropriate offset) I see the
proper beacon frames being transmitted now.

A crash reported on freebsd-fs@ on Sep. 23, 2011 under the subject
heading "kernel panics with RPCSEC_GSS" appears to be caused by a
corrupted tailq list for the client structure. Looking at the code, calls
to the function svc_rpc_gss_forget_client() were done in an SMP unsafe
manner, with the svc_rpc_gss_lock only being acquired in the function
and not before it. As such, when multiple threads called
svc_rpc_gss_forget_client() concurrently, it could try and remove the
same client structure from the tailq lists multiple times.
The patch fixes this by moving the critical code into a separate
function called svc_rpc_gss_forget_client_locked(), which must be
called with the lock held. For the one case where the caller would
have no interest in the lock, svc_rpc_gss_forget_client() was retained,
but a loop was added to check that the client structure is still in
the tailq lists before removing it, to make it safe for multiple
concurrent calls.
