glx/drisw: return false if shmid == -1
If an attempt to create an shm pixmap in XCreateDrawable fails then it ends up with the shmid == -1. This means the get image path needs to fallback so return false in this case to use the non-shm get image path. Fixes: 02c3dad0f3b4 ("Call shmget() with permission 0600 instead of 0777") Reviewed-by: Michel Dänzer <[email protected]> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/merge_requests/3823>
