qcacld-3.0: Cleanup all NDPs as part of NAN disable

NDPs can exist on an NDI only when the NAN discovery is active.
Currently, firmware sends NDP_END indication for all NDPs when NAN
is disabled. Host driver removes the NDI entry from the policy mgr
based on these NDP_END indications. But firmware might miss to send
the NDP_END indication in some cases though the NDPs are deleted
in firmware. This leads to stale NDI entries in the policy mgr and
it prevents STA connections as NDI+STA without NAN discovery is not
a valid concurrency.
Host driver can remove all NDPs before sending NAN disable request
to firmware to avoid this. This is a blocking call in driver and
wait for the NDP_HOST_UPDATE event from firmware. Cleanup the policy
mgr entries in timeout case as well to avoid further failures due
to unsupported concurrency.
