Windows: Fix no longer receive data after EV_TXEMPTY triggered for CDC ACM devicev5.1.0-rc2v5.1.0-rc1v5.1.0
A previous patch
* SHA1 ID: 2bcac223e64599eb74889975053f6547000b13cb
introduced a regression: after triggering of EV_TXEMPTY a reception of
data is stopped. The reason for this was an immediate return from the
handler processCompletionRoutine().
The solution - do not do an immediate return and let to call method
startAsyncRead().
Thanks to Dan
