From: Alex Wu <zhiwen...@intel.com>
If the scanout client was interrupted (e.g. by Ctrl-C),
compositor-drm.c::page_flip_handler()
was not guaranteed to be invoked for the last scanout
drmModePageFlip(), so that pending_fs_surf_fb_id
has no chance to reset to 0, and the output will still scanout the old
framebuffer with pending_fs_surf_fb_id.
