iw_cxgb4: Fix potential NULL dereference in c4iw_fill_res_cm_id_entry()

Browse source

[ Upstream commit 4ca446b127 ]

This condition needs to match the previous "if (epcp->state == LISTEN) {"
exactly to avoid a NULL dereference of either "listen_ep" or "ep". The
problem is that "epcp" has been re-assigned so just testing
"if (epcp->state == LISTEN) {" a second time is not sufficient.
