iwlwifi: update reply_statistics_cmd with 'clear' parameter
When issue REPLY_STATISTICS_CMD to uCode, two possible flag
can be set in the configuration flags
bit 0: Clear statistics
0: Do not clear Statistics counters
1: Clear to zero Statistics counters
Allow "clear" parameter to be set from the caller.
Add debugfs file to clear the statistics counters to help monitor and
debug the uCode behavior.
