qcacld-3.0: Refactor WE_SET_AMPDU ioctl processing

One of the HDD functions with the highest cyclomatic complexity is
__iw_setint_getnone(). In order to reduce the complexity there is a
plan to replace the existing switch with a vtable. As part of that
goal refactor the WE_SET_AMPDU ioctl handling into a separate
function.
