qcacld-3.0: Avoid info leak in hdd_driver_rxfilter_comand_handler

Browse source 
In hdd_driver_rxfilter_comand_handler(), when kstrtou8() fails to parse
the input string, the value of an uninitialized @type local is logged.
To avoid leaking stack memory, avoid logging the value of @type if the
parsing fails.
