eglglessink: Fix setup chain logic

Browse source 
Mostly a procedural reordering. Idea is to avoid
trying to setup a surface without a display.This
change relies on the asumption that:

1.- set_window_handle() can happen at any time
2.- setcaps will never get called before _start()
    is done.

If both conditions are meet the new procedure
should work as expected.
