NsdService does not clean up after exiting clients

When a client of the NsdService exits, NsdService should
clean up the requests it has sent to the mDNS daemon:
cancel any pending resource-discovery and resource-resolution
queries, and remove any services registered by this client.

If this isn't done, several bad things happen. The daemon will
continue to run unnecessarily, will report service discoveries
that can't be forwarded on to the client, and will continue to
advertise service ports for an application which is no longer
running until the device is rebooted (mDNS pollution).

Fix WifiHandler for MSim

Commit 7c26a5cce74332bc48da9e894a835f2fe795431c attempted to fix
this issue by adding back the old code, but it needs to be a method
that can be called by MSimNetworkController. So sync it back to caf
to fix the merge issue.
