Log:

Minor speedup for LiveTV channel changes

No functional changes, mainly just a reordering of a couple things.

The autoexpirer update can take a while so do it after returning the
livetv directory to the requesting TVRec. Also, use a wait condition
instead of a loop with usleep and dispatch the request for the next
livetv directory asap because it can take some time.

YMMV on how much this will improve channel change times. There are
many factors involved such as storage group configuration, file system
utilization, system load, number of cpu cores, etc.
