Subject: [net-next 02/15] ice: Fix resource leak in ice_remove_rule_internal()

From: Jeb Cramer <jeb.j.cramer@...el.com>

We don't free s_rule if ice_aq_sw_rules() returns a non-zero status.  If
it returned a zero status, s_rule would be freed right after, so this
implies it should be freed within the scope of the function regardless.
