iwlwifi: mvm: enable watchdog on Tx queues for mvm
This watchdog allows to monitor the transmit queues. When a queue doesn't progress for a too long time, a timer fires and then, debug data can be collected. This watchdog has never been enabled on dvm controlled devices, so don't enable it there. In order to have it running on mvm controlled devices, we need to fix a small issue in the transport layer: mvm controlled devices use the shadow registers optimization. In this case, the watchdog wasn't running at all, even if enabled by the module parameter. Fix that on the way.
