qcacld-3.0: Update NDP peer MC list

Browse Source 
Currently, driver gets peer multicast address list from kernel for
all interfaces and it send this list to firmware. For NDI, on NDP
confirmation indication, driver appends the multicast list with
new NDP peer added and then send it to firmware. But this is done
for first NDP peer only, kernel does not provide multicast list
again as kernel already configures the multicast addresses, unless
there is some reset happens in kernel.
This can cause issue as firmware is expecting the updated multicast
filter on each NDP confirmation (new peer is added) to enable the
NS frame exchange. As new peer is not added in the filter, firmware
will reject the NS frame.

So, to fix this, update the multicast list on NDP peer addition and
deletion.
