[PATCH 24/44] RDMA/mana_ib: Use v2 version of cfg_rx_steer_req to enable RX coalescing

With RX coalescing, one CQE entry can be used to indicate multiple packets
on the receive queue. This saves processing time and PCI bandwidth over
the CQ.

The MANA Ethernet driver also uses the v2 version of the protocol. It
doesn't use RX coalescing and its behavior is not changed.
