description:
Fix bug in error handling for NFSv3 + nqnfs.
With nfsv2, the nfsm_reply() macro always causes the service routine
to return if error was nonzero.

With nfsv3, we can keep going after nfsm_reply() without returning,
but nqnfsrv_getlease() didn't take this into account, so add a
return(0) after each error-case nfsm_reply(0).
