[PATCH 4.16 214/279] qede: Fix gfp flags sent to rdma event node allocation

[Greg Kroah-Hartman]

4.16-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Michal Kalderon <Michal.Kalderon@xxxxxxxxxx>

[ Upstream commit 090477e4acb31c5dd674940c7c01d4f16bd1ac41 ]

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.
