knfsd: nfsd: provide export lookup wrappers which take a svc_rqst
Split the callers of exp_get_by_name(), exp_find(), and exp_parent() into
those that are processing requests and those that are doing other stuff (like
looking up filehandles for mountd).
No change in behavior, just a (fairly pointless, on its own) cleanup.
(Note this has the effect of making nfsd_cross_mnt() pass rqstp->rq_client
instead of exp->ex_client into exp_find_by_name(). However, the two should
have the same value at this point.)
