[PATCH] nfsd4: return better error on io incompatible with open mode
from RFC 3530:
"Share reservations are established by OPEN operations and by their
nature are mandatory in that when the OPEN denies READ or WRITE
operations, that denial results in such operations being rejected
with error NFS4ERR_LOCKED."
(Note that share_denied is really only a legal error for OPEN.)
