drivers/infiniband/ulp/srpt/ib_srpt.c: fix build with gcc-4.4.4



gcc-4.4.4 has issues with initialization of anonymous unions:

drivers/infiniband/ulp/srpt/ib_srpt.c: In function 'srpt_zerolength_write':
drivers/infiniband/ulp/srpt/ib_srpt.c:854: error: unknown field 'wr_cqe' specified in initializer
drivers/infiniband/ulp/srpt/ib_srpt.c:854: warning: initialization makes integer from pointer without a cast

Work aound this.
