drivers/infiniband/core/verbs.c: fix build with gcc-4.4.4

commit 6ee687735e745eafae9e6b93d1ea70bc52e7ad07 upstream.

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.
