[ Upstream commit 03e9b33a0fd677f554b03352646c13459bf60458 ]
While adding a path from the client side to an already established
session, it was possible to provide the destination IP to a different
server. This is dangerous.
This commit adds an extra member to the rtrs_msg_conn_req structure, named
first_conn; which is supposed to notify if the connection request is the
first for that session or not.
On the server side, if a session does not exist but the first_conn
received inside the rtrs_msg_conn_req structure is 1, the connection
request is failed. This signifies that the connection request is for an
already existing session, and since the server did not find one, it is an
wrong connection request.

[ Upstream commit 7490fd1fe836ba3c7eda7a4b1cfd9e44389ffda5 ]
rtrs does not have same limit for both max_send_wr and max_recv_wr,
To allow client and server set different values, export in a separate
parameter for rtrs_cq_qp_create.
Also fix the type accordingly, u32 should be used instead of u16.
