nfsd: revert v2 half of "nfsd: don't return high mode bits"
commit 082f31a2169bd639785e45bf252f3d5bce0303c6 upstream.
This reverts the part of commit 6e14b46b91fee8a049b0940333ce13a820beaaa5
that changes NFSv2 behavior.
Mark Lord found that it broke nfs-root for Linux clients, because it
broke NFSv2.
In fact, from RFC 1094:
"Notice that the file type is specified both in the mode bits
and in the file type. This is really a bug in the protocol and
will be fixed in future versions."
So NFSv2 clients really are expected to depend on the high bits of the
mode.
