BUG/MINOR, BUG/MINOR: lua: Put tasks to sleep when waiting for data 

If a lua socket is waiting for data it currently spins at 100% cpu usage.
This because the TICK_ETERNITY returned by the socket is ignored when
setting the 'expire' time of the task.

Fixed by removing the check for yields that return TICK_ETERNITY.

This should be backported to at least 1.8.
