red_worker: revert 8855438a

red_proccess_commands calls were added after calling
guest_set_client_capabilities in order to cleanup the command ring from
old commands that the client might not be able to handle.
However, calling red_process_commands at this stage does send messages
to the client.
In addition, since setting the client capabilities at the guest is not
synchronized, emptying the command ring is not enough in order to make
sure the following commands will be supported by the client.
The call to red_proccess_commands before initializing the display
streams (the call to red_display_start_streams), caused inconsistencies
related to video streaming upon reconnecting (rhbz#883564).

I'm reverting this patch till another solution for the capabilities
mismatch is introduced.

Resolves: rhbz#883564
