RDMA/vmw_pvrdma: Fix network_hdr_type reported in WC
commit 9f206f7398f6f6ec7dd0198c045c2459b4f720b6 upstream.
The PVRDMA device HW interface defines network_hdr_type according to an
old definition of the internal kernel rdma_network_type enum that has
since changed, resulting in the wrong rdma_network_type being reported.
Fix this by explicitly defining the enum used by the PVRDMA device and
adding a function to convert the pvrdma_network_type to rdma_network_type
enum.
Cc: stable@vger.kernel.org # 5.10+
Fixes: 1c15b4f2a42f ("RDMA/core: Modify enum ib_gid_type and enum rdma_network_type")
