Patch for RPI crash

[Yves De Muyter]

Hello,

Here is a fix for an issue that pops up here when I close a window on a
Raspberry-pi that is using GLES2 to draw contents.
It also reproducible with the clients/simple-egl application by simply
pressing 'esc' on the window (closes the window) or doing 'ctrl-c' on
the terminal. The result is a Weston crash.

What happens is that the buffer is set to NULL while still used.
The patch is against current master.
