qcacld-3.0: Refactor "set vdev" 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 "set vdev" ioctl handling into separate functions.
