RDMA/hns: Fix error return code in hns_roce_v1_rsv_lp_qp()

Fix to return error code -ENOMEM from the rdma_zalloc_drv_obj() error
handling case instead of 0, as done elsewhere in this function.

Fixes: e8ac9389f0d7 ("RDMA: Fix allocation failure on pointer pd")
Fixes: 21a428a019c9 ("RDMA: Handle PD allocations by IB/core")
