qcacmn: Use API policy_mgr_get_can_skip_radar_event for Radar event

Dfs radar processing function dfs_process_radar_ind is called
in interrupt context. Add new API policy_mgr_get_can_skip_radar_event
to be called in interrupt context to get radar skip flag.
The policy_mgr_get_dfs_master_dynamic_enabled will acquire mutex and can't
be called in interrupt context.
