cxgb4: fix regression with HASH tc prio value update

Browse source

[ Upstream commit a27fb314cb ]

commit db43b30cd8 ("cxgb4: add ethtool n-tuple filter deletion")
has moved searching for next highest priority HASH filter rule to
cxgb4_flow_rule_destroy(), which searches the rhashtable before the
the rule is removed from it and hence always finds at least 1 entry.
Fix by removing the rule from rhashtable first before calling
cxgb4_flow_rule_destroy() and hence avoid fetching stale info.
