Subject: ib_srpt: Destroy cm_id before destroying QP.
From: Nicholas Bellinger <[email protected]>
commit 0b41d6ca616ddeb3b6c0a80e8770b6f53cd42806 upstream.
This patch fixes a bug where ib_destroy_cm_id() was incorrectly being called
after srpt_destroy_ch_ib() had destroyed the active QP.
This would result in the following failed SRP_LOGIN_REQ messages:
