nfscl: Fix setting of nfsess_defunct for nfscl_hasexpired()
Commit a7bb120f8b87 added a printf for the case where recovery
has not marked the session defunct by setting nfsess_defunct
to 1. It turns out that nfscl_hasexpired() calls
nfsrpc_setclient() directly, without setting nfsess_defunct.
This patch replaces the printf with code that sets
nfsess_defunct to 1 to handle this case.
If SIGTERM is issued to a process when it is doing I/O on
an "intr" mount, the NFSv4 server may reply NFSERR_BADSTATEID,
due to the Open being prematurely closed.
This can result in a call to nfscl_hasexpired() to do a
recovery.
This would explain at least one hang described in the PR.
