ui/vnc-enc-tight: remove switch and have single return

Browse Source 
When enabling the sanitizer build it will complain about control
reaching a non-void function. Normally the compiler should detect that
there is only one possible exit given a static VNC_SERVER_FB_BYTES.

As we always expect a static VNC_SERVER_FB_BYTES I've added a compile
time assert and just called the sub-function directly.
