qcacld-3.0: BPF fixes for check connection state, set maxwow filter

Browse source 
qcacld-2.0 to qcacld-3.0 propagation

* Set BPF filter only if the station/p2p client is in the connected
  state.
* Depending on the BPF service enabled in firmware dynamically
  configure the number of wow filters.
    - If bpf enabled maxwowfilter is 2.
    - If bpf is disabled maxwowfilter is read from ini.
