    RDMA/hns: Fix inappropriate err code for unsupported operations
    
    [ Upstream commit f45b83ad39f8033e717b1eee57e81811113d5a84 ]
    
    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")
