Subject: scsi: qedf: Honor qed_ops->common->set_fp_int() return code.
Patch-mainline: v4.13-rc1
Git-commit: 914fff102e00455bb867871e612b65524839d271
References: bsc#1040813
We need to check the return code the set_fp_int() callback in case we were
not allocated any fastpath interrupts or there was an error setting up the
fastpath interrupts from the qed perspective.
