Bug#1105161: freerdp3-x11: freerdp3 needlessly prompts for domain even when it is already provided by param /u

[Elias Batek]

So, the UX issue here is that people used to the FreeRDP 2 workflow will 
accidentally type or paste the password in the cleartext domain prompt. 
(Unlike with the password prompt where user input is invisible, the 
input for the domain prompt is shown verbatim on screen.)

Best regards,
