qcacld-3.0: Refactor WE_PPS_* processing

One of the HDD functions with the highest cyclomatic complexity is
__iw_setint_getnone(). The handing of all of the WE_PPS_* sub-ioctls
has a complexity greater than 1, so refactor that logic into separate
functions to help reduce the complexity of __iw_setint_getnone().
