missing nfserrno() in default case of a switch by return value of
posix_lock_file(); as the result we send negative host-endian to clients that
expect positive network-endian, preferably mentioned in RFC...  BTW, that case
is not impossible - posix_lock_file() can return -ENOLCK and we do not handle
that one explicitly.
