The call netdev_{put, hold} of dev_{put, hold} will check NULL,
so there is no need to check before using dev_{put, hold},
remove it to silence the warning:

'device' argument is never used since rdma_build_skb()
is introduced, so remove it.

Add support to get the RoCE LAG xmit slave by building skb of the RoCE
packet and call to master_get_xmit_slave. If driver wants to get the
slave assume all slaves are available, then need to set
RDMA_LAG_FLAGS_HASH_ALL_SLAVES in flags.
