netfilter: x_tables: don't return garbage pointer on modprobe failure
request_module may return a positive error result from modprobe,
if we cast this to ERR_PTR this returns a garbage result (it passes
IS_ERR checks).
Fix it by ignoring modprobe return values entirely, just retry the
table lookup instead.
