wifi: iwlegacy: fix broadcast stations deallocation

Type: advisorySource: Official CVE List1 source record

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlegacy: fix broadcast stations deallocation On the error path of __il4965_up(), il_dealloc_bcast_stations() clears only IL_STA_UCODE_ACTIVE, leaving IL_STA_BCAST set. This causes the same broadcast stations to be deallocated again by __il4965_down(). This can occur when RF_KILL is toggled during driver startup. To fix clear the entire 'used' field, since we will not do any other operations on the station.
