qcacld-3.0: In PMO, replace cfg_get_int with component cfg API's

Legacy WNI CFG items are refactored into new CFG implementation.
PMO uses a wma callback which uses cfg_get API to get listen
interval. Listen interval is now part of the MLME component's
private object. Define API's to get this value and use it instead
of the callbacks.

Remove WMA callback implementation and use new API that gets
listen interval from MLME component.
