RDMA/hns: Check return value of kzalloc
When lp_qp_work is NULL, we should return ENOMEM. In order to do so,
we had to make some upper layer functions return a value instead
of being void type so we can propagate the error up the stack.
This patch fixes the smatch error as below:
drivers/infiniband/hw/hns/hns_roce_hw_v1.c:918 hns_roce_v1_recreate_lp_qp()
error: potential null dereference 'lp_qp_work'. (kzalloc returns null)
