From: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx>
Subject: drivers/infiniband/core/verbs.c: fix build with gcc-4.4.4

gcc-4.4.4 has issues with initialization of anonymous unions.

drivers/infiniband/core/verbs.c: In function '__ib_drain_sq':
drivers/infiniband/core/verbs.c:2204: error: unknown field 'wr_cqe' specified in initializer
drivers/infiniband/core/verbs.c:2204: warning: initialization makes integer from pointer without a cast

Work around this.

Fixes: a1ae7d0345edd5 ("RDMA/core: Avoid that ib_drain_qp() triggers an out-of-bounds stack access")
