Subject: qed: Enable RoCE parser searching on fp init
Patch-mainline: v4.13-rc1
Git-commit: f855df220238436d10c3de67da0b1a280a2092b4
References: bsc#1050536 FATE#322898 bsc#1050538 FATE#322897
Since we're closing the parser searching for RDMA when stoping the
fastpath, we need to re-enable it when starting the fastpath once again.
