qcacld-3.0: Relocate hdd_statistics_cb()

Function hdd_statistics_cb() is registered as a callback function by
__iw_get_statistics() when calling sme_get_statistics(). Since
hdd_statistics_cb() and __iw_get_statistics() are tightly coupled it
makes sense for them to be co-located, but currently they are
not. Therefore relocate hdd_statistics_cb() to be adjacent to
__iw_get_statistics(). Note that this is a precursor to further
cleanup of this pair of functions.
