[PATCH AUTOSEL 4.18 66/76] nds32: fix logic for module

[Sasha Levin]

From: Greentime Hu <greentime@xxxxxxxxxxxxx>

[ Upstream commit 1dfdf99106668679b0de5a62fd4f42c1a11c9445 ]

This bug is report by Dan Carpenter. We shall use ~loc_mask instead of
!loc_mask because we need to and(&) the bits of ~loc_mask.
