qcacld-3.0: CONFIG_MCL cleanup for Serialization msg queue depth

Remove CONFIG_MCL for Serialization msg queue depth to make code generic.
Initialize value for Serialization msg queue depth i.e
SCHEDULER_CORE_MAX_MESSAGES to 1000 for MCL. In case
SCHEDULER_CORE_MAX_MESSAGES not defined, then
SCHEDULER_CORE_MAX_MESSAGES define to 4000 for WIN.
