qcacmn: Fix for sending valid monitor filter setting to FW

Due to usage of lithium specific structure, the filter settings
were not getting reflected in the htt msg that is being sent to
FW. Usage of BE specific monitor pdev structure is helping out
in configuring the monitor filter settings for various modes.
