RDMA/erdma: Add connection management (CM) support

Browse source

ERDMA's transport protocol is iWarp, so the driver must support CM
interface. In CM part, we use the same way as SoftiWarp: using kernel
socket to set up the connection, then performing MPA negotiation in
kernel. So, this part of code mainly comes from SoftiWarp, base on it,
we add some more features, such as non-blocking iw_connect implementation.

This commit also fixes a duplicated include issue reported by Abaci Robot.
