RDMA/ionic: Preserve and set Ethernet source MAC after ib_ud_header_init()
ionic_build_hdr() populated the Ethernet source MAC (hdr->eth.smac_h) by
passing the header’s storage directly to rdma_read_gid_l2_fields().
However, ib_ud_header_init() is called after that and re-initializes the
UD header, which wipes the previously written smac_h. As a result, packets
are emitted with an zero source MAC address on the wire.
Correct the source MAC by reading the GID-derived smac into a temporary
buffer and copy it after ib_ud_header_init() completes.
