RDMA/hns: Fix inappropriate err code for unsupported operations

EOPNOTSUPP is more situable than EINVAL for allocating XRCD while XRC
is not supported and unsupported resizing SRQ.

Fixes: 32548870d438 ("RDMA/hns: Add support for XRC on HIP09")
Fixes: 221109e64316 ("RDMA/hns: Add interception for resizing SRQs")
