There were three paths that called eglDestroyImageKHR:
* The front buffer
* The intel driver's flip buffer
* pixmaps under DRI3
This patch unifies the second two by having glamor_destroy_pixmap
always destroy any associaged EGL image. This allows us to stop
storing the back_pixmap pointer in glamor as that was only used to
make sure that buffer was freed at server reset time.
v2: check for valid pixmap_priv before using it in
glamor_egl_destroy_pixmap_image
