nfsd4: fix READ permission checking

commit 6e4891dc289cd191d46ab7ba1dcb29646644f9ca upstream.

In the case we already have a struct file (derived from a stateid), we
still need to do permission-checking; otherwise an unauthorized user
could gain access to a file by sniffing or guessing somebody else's
stateid.

Fixes: dc97618ddda9 "nfsd4: separate splice and readv cases"
