IB/cm: Fix automatic path migration support
The ib_cm_establish() function is replaced with a more generic
ib_cm_notify(). This routine is used to notify the CM that failover
has occurred, so that future CM messages (LAP, DREQ) reach the remote
CM. (Currently, we continue to use the original path) This bumps the
userspace CM ABI.
New alternate path information is captured when a LAP message is sent
or received. This allows QP attributes to be initialized for the user
when a new path is loaded after failover occurs.
