From: Hans Verkuil hansverk@cisco.com
[ Upstream commit 120476123646ba3619c90db7bcbc6f8eea53c990 ]
When a pending message was canceled (e.g. due to a timeout), then the old tx_status info was overwritten instead of ORed. The same happened with the tx_error_cnt field. So just modify them instead of overwriting them.
