iwlwifi: add num_of_sos_stats to statistics counter

Browse Source 
When uCode detects number of beacon missed consecutively above the
internal missed beacon threshold (set by uCode), it will reset and
re-tune the radio in order to get out of bad PHY state.

This "num_of_sos_states" counter monitors number of time uCode
encounters this bad condition and has to re-tune the radio.
