migration: do not wait for free thread
Instead of putting the main thread to sleep state to wait for
free compression thread, we can directly post it out as normal
page that reduces the latency and uses CPUs more efficiently
A parameter, compress-wait-thread, is introduced, it can be
enabled if the user really wants the old behavior
