audit: return on memory error to avoid null pointer dereference
If there is a memory allocation error when trying to change an audit
kernel feature value, the ignored allocation error will trigger a NULL
pointer dereference oops on subsequent use of that pointer. Return
instead.
Passes audit-testsuite.
