wifi: iwlwifi: mvm: reset the smart fifo state upon FW stop

Browse Source 
The smart fifo is a feature in the firmware configured by the driver.
The driver keeps a state to remember what was the last configuration
sent to the firmware. Obviously, if the firmware stops, we need to
reconfigure the smart fifo. Since we didn't reset that state upon
firmware stop, we thought the firmware is already properly
configured and we didn't send the smart fifo configuration command
as part of the init sequence.

Reset the smart fifo state in iwl_mvm_stop_device() so that we
will properly send the command during the init that will come
later.
