RDMA/hns: Fix a missing rollback in error path of hns_roce_create_qp_common() 

driver inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/IBSE4C



----------------------------------------------------------------------

When ib_copy_to_udata() fails in hns_roce_create_qp_common(),
hns_roce_qp_remove() should be called in the error path to
clean up resources in hns_roce_qp_store().

Fixes: 0f00571f ("RDMA/hns: Use new SQ doorbell register for HIP09")
