qcacld-3.0: Refactor WE_SET_DATA_INACTIVITY_TO processing

Currently the HDD function with the highest cyclomatic complexity is
__iw_setint_getnone(). The handing of WE_SET_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().
