ath9k: ar5008_hw_cmn_spur_mitigate: add missing mask_m & mask_p initialisation 

by moving common code to ar5008_hw_cmn_spur_mitigate i forgot to move
mask_m & mask_p initialisation. This coused a performance regression
on ar9281.

Fixes: f911085ffa ("ath9k: split ar5008_hw_spur_mitigate and reuse common code in ar9002_hw_spur_mitigate.")
