FreeRDP/client/X11/xf_client.c
Armin Novak c3a26b0d6a Removed +async-transport options 
The async transport option is broken by design.
If used the main loop is called from the transport thread and the
main thread of the application.
Unless the transport layer is refactored to just work on queues
(input and output) this option will never work, therefore remove it.
