nfscl: Fix handling of nd_slotid while handling NFSERR_BADSESSION
When the NFSv4.1/4.2 client is handling a server error
of NFSERR_BADSESSION, it retries RPCs with a new session.
Without this patch, the nd_slotid was not being updated
for the new session.
This would result in a bogus console message like
"Wrong session srvslot=X slot=Y" and then it would
free the incorrect slot, often generating a
"freeing free slot!!" console message as well.
This patch fixes the problem.
Note that FreeBSD NFSv4.1/4.2 servers only
generate a NFSERR_BADSESSION error after a reboot
or after a client does a DestroySession operation.
