NFS: Fix up new minorversion= option

Browse Source 
The new minorversion= mount option (commit 3fd5be9e) was merged at
the same time as the recent sloppy parser fixes (commit a5a16bae),
so minorversion= still uses the old value parsing logic.

If the minorversion= option specifies a bogus value, it should fail
with "bad value" not "bad option."
