WifiServiceImpl: update API for LOHS

Add a return code for disallowed tethering for the user.  Since this
needs to be a new failure mode, the return type for starting LOHS needed
to change.  Updated tests to reflect this as well.

This CL will be part of a topic - there is a corresponding WifiManager
change.
