Make some changes to some additions I made recently for doing channel autoservice

when looking up extensions.  This code was added to handle the case where a
dialplan switch was in use that could block for a long time.  However, the way
that I added it, it did this for all extension lookups.  However, lookups in the
in-memory tree of extensions should _not_ take long enough to matter.  So, move
the autoservice stuff to be only around executing a switch.
