rxe_set_mtu() will call rxe_info_dev() to print message, and
rxe_info_dev() expects dev_name(rxe->ib_dev->dev) has been assigned.
Previously since dev_name() is not set, when a new rxe link is being
added, 'null' will be used as the dev_name like:
"(null): rxe_set_mtu: Set mtu to 1024"
Move rxe_register_device() earlier to assign the correct dev_name
so that it can be read by rxe_set_mtu() later.
And it's safe to do such change since mtu will not be used during the
rxe_register_device()
After this change, message becomes:
"rxe_eth0: rxe_set_mtu: Set mtu to 4096"
