Olivier Fourdan b3635ba69e glamor: Fix possible double-free 
If glamor_link_glsl_prog() fails, we may jump to the failed code path
which frees the variable vs_prog_string and fs_prog_string.

But those variables were already freed just before, so in that case we
end up freeing the memory twice.

Simply move the free at the end of the success code path so we are sure
to free the values only once, either in the successful of failed code
paths.

Fixes: 2906ee5e4 - glamor: Fix leak in glamor_build_program()
Signed-off-by: Olivier Fourdan <ofourdan@redhat.com>
(cherry picked from commit 34ea020344)

X Server

The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into.

Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.

For a comprehensive overview of X Server and X Window System, consult the following article: https://en.wikipedia.org/wiki/X_server

All questions regarding this software should be directed at the Xorg mailing list:
