Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit b1a4da64bfc189510e08df1ccb1c589e667dc7a3 ]
Fix the wrongly reported max_send_wr and max_recv_wr attributes for user QP by making sure to save their valuse on QP creation, so when query QP is called the attributes will be reported correctly.
