qcacmn: Remove NDP_HOST_UPDATE processing

Browse Source 
Firmware sends NDP_HOST_UPDATE event as an immediate response to this
request and starts cleaning peers one by one. Once an NDP session is
ended (indicating NDP_END to peer + internal cleanup), firmware sends
NDP_END_IND to host.
Currently, host driver stops the wait timer and change state from NDP
end to disconnected upon receiving the NDP_HOST_UPDATE. But firmware
might still be in the process of NDP cleanup. As the NDP_END_ALL
context is unblocked, driver may send NAN disable request to firmware.
This may cause inconsistency in firmware state machine and firmware may
drop the ongoing NDP_END request. So, peer doesn't get the NDP_END frame
in such cases.
Unblock the NDP_END_ALL-wait call only upon last NDP_END indication to
avoid such issues. This change moves the major functionality of
NDP_HOST_UPDATE processing to last NDP_END indication. Cleanup/remove
the processing of NDP_HOST_UPDATE as it's not needed anymore.
