Subject: RDMA/cxgb4: Restore the dropped uninitialized_var
Patch-mainline: v4.19-rc1
Git-commit: 23ff6ba8feec5c4bdf993af3fba3937d57883dc8
References: bsc#1104276 FATE#325935

In some configurations even gcc 7 cannot unravel this complexity and still
throws a warning.

Fixes: 4ab39e2f98f2 ("RDMA/cxgb4: Make c4iw_poll_cq_one() easier to analyze")
