Correct the logic of glamor_egl_create_textured_pixmap.

Browse Source 
Discussed with Chris and found the previous logic is not
good. Now change it in this commit, this API will just
try to create a textured pixmap from the handle provided
by DDX driver, if failed simply return FALSE without touch
the pixmap. And the DDX driver can choose how to do next
step.
