qcacld-3.0: Rename legacy definitions containing BPF to APF

In implementation of Android Packet Filter, functions, variables,
definitions are named after BPF, which stands for Berkely Packet
Filter. The term was more appropriate for Link Layer packet
filters implemented in the Linux kernel, known as Linux Socket
Filters.

The term BPF is obsolete now, so rename it with the
appropriate acronym, APF.
