[PATCH -v1 2/3] vm: use new has_capability_noaudit

[Eric Paris <eparis@redhat.com>]

The oomkiller calculations make decisions based on capabilities.  Since
these are not security decisions and LSMs should not record if they fall
the request they should use the new has_capability_noaudit() interface so
the denials will not be recorded.
