Subject: ima/policy: fix parsing of fsuuid

From: Mike Rapoport <rppt@linux.vnet.ibm.com>

commit 36447456e1cca853188505f2a964dbbeacfc7a7a upstream.

The switch to uuid_t invereted the logic of verfication that &entry->fsuuid
is zero during parsing of "fsuuid=" rule. Instead of making sure the
&entry->fsuuid field is not attempted to be overwritten, we bail out for
perfectly correct rule.
