Unset the gss kernel state when gssd exits

When gssd exits it leaves the kernel state set by
gssd_syscall().  nfsd sees this and waits endlessly
in an unkillable state for gssd to come back.  If you
had acidentally started gssd then stopped it, then
started nfsd you'd be in a bad way until you either
restarted gssd or rebooted the system.  This change
fixes that by setting the kernel state to "" when
gssd exits.
