[PATCH 010 of 14] knfsd: nfsd4: fix some open argument tests

[NeilBrown <neilb@suse.de>]

From: J. Bruce Fields <bfields@citi.umich.edu>


These tests always returned true; clearly that wasn't what was intended.

In keeping with kernel style, make them functions instead of macros while
we're at it.
