Both im_intfr_cnt and im_samp_cnt need to store for following
dcs event process, dcs_im_stats is a local variable, so both
im_intfr_cnt and im_samp_cnt value will be missing when function
wlan_dcs_wlan_interference_process return.
Fix is to define pointer p_dcs_im_stats for use.

For MCL side, WLAN_UMAC_MAX_PDEVS is always 1 from current design,
so it's wrong to use WLAN_UMAC_MAX_PDEVS define array dcs_pdev_priv,
since dcs_pdev_priv includes firmware indicated pdev dcs information,
define WLAN_DCS_MAX_PDEVS to 3 for dcs use, this will be compatible
for both MCL and WIN side.
