qcacld-3.0: CONFIG_MCL cleanup for WLAN_SCHED_REDUCTION_LIMIT

Remove CONFIG_MCL for reduction limit to make code generic.
Initialize value for reduction limit  i.e WLAN_SCHED_REDUCTION_LIMIT
to 0 for MCL. In case WLAN_SCHED_REDUCTION_LIMIT not defined, then
define WLAN_SCHED_REDUCTION_LIMIT to 32 for WIN.
