Subject: qede: Fix gfp flags sent to rdma event node allocation
Patch-mainline: v4.17-rc5
Git-commit: 090477e4acb31c5dd674940c7c01d4f16bd1ac41
References: bsc#1050538 FATE#322897 bsc#1050545 FATE#322893

A previous commit 4609adc27175 ("qede: Fix qedr link update")
added a flow that could allocate rdma event objects from an
interrupt path (link notification). Therefore the kzalloc call
should be done with GFP_ATOMIC.
