mac80211: Fix signal strength average initialization for CQM events
The ave_beacon_signal value uses 1/16 dB unit and as such, must be initialized with the signal level of the first Beacon frame multiplied by 16. This fixes an issue where the initial CQM events are reported incorrectly with a burst of events while the running average approaches the correct value after the incorrect initialization. This could cause user space -based roaming decision process to get quite confused at the moment when we would like to go through authentication and DHCP.
