Subject: NFSD: fix nfsd_minorversion(.., NFSD_AVAIL)
From: NeilBrown <neilb@xxxxxxxx>
[ Upstream commit 928c6fb3a9bfd6c5b287aa3465226add551c13c0 ]
Current code will return 1 if the version is supported,
and -1 if it isn't.
This is confusing and inconsistent with the one place where this
is used.
So change to return 1 if it is supported, and zero if not.
i.e. an error is never returned.
