Ondrej Mosnacek af091cc27e selinux: fix misuse of mutex_is_locked()
commit ce2fc710c9d2b25afc710f49bb2065b4439a62bc upstream.

mutex_is_locked() tests whether the mutex is locked *by any task*, while
here we want to test if it is held *by the current task*. To avoid
false/missed WARNINGs, use lockdep_assert_is_held() and
lockdep_assert_is_not_held() instead, which do the right thing (though
they are a no-op if CONFIG_LOCKDEP=n).
