Subject: ath9k: ar5008_hw_cmn_spur_mitigate: add missing mask_m & mask_p initialisation

From: Oleksij Rempel <[email protected]>

commit de478a61389cacafe94dc8b035081b681b878f9d upstream.

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.
