qcacld-3.0: Refactor WE_SET_WOW_DATA_INACTIVITY_TO processing

Currently the HDD function with the highest cyclomatic complexity is
__iw_setint_getnone(). The handing of WE_SET_WOW_DATA_INACTIVITY_TO
has a complexity greater than 1, so refactor that logic into a
separate function to help reduce the complexity of
__iw_setint_getnone().
