wifi: iwlwifi: Ensure ack flag is properly cleared.

Browse source 
[ Upstream commit e8fbe99e87877f0412655f40d7c45bf8471470ac ]

Debugging indicates that nothing else is clearing the info->flags,
so some frames were flagged as ACKed when they should not be.
Explicitly clear the ack flag to ensure this does not happen.
