[openib-general] potential bug: ipoib freeing ah before completion

[Michael S. Tsirkin]

Hello, Roland!
The following was noted by Eli Cohen:

It seems that ipoib_flush_paths can be called while completions are still
outstanding on IPoIB QP (e.g. from ipoib_ib_dev_flush). If this happens, an
address handle might get freed while a work request is still outstanding for it.
This can trigger a local QP error, and IPoIB will stop working, until QP
is reset.

Please comment.
