UPSTREAM: fib_rules: fix error in backport of e9919a24d302 ("fib_rules: return 0...")

When commit e9919a24d302 ("fib_rules: return 0 directly if an exactly
same rule exists when NLM_F_EXCL not supplied") was backported to 4.9.y,
it changed the logic a bit as err should have been reset before exiting
the test, like it happens in the original logic.

If this is not set, errors happen :(
