i965: Reset miptree aux state on update_image_buffer
When we get a miptree in through glxBindImageEXT, we don't know the
current aux state so we have to assume the worst-case. If the image
gets recreated, everything is fine because miptreecreate_for_dri_image
sets it to the default. However, if our miptree is recycled, then we
may have stale aux_usage and we need to reset to the default otherwise
our aux_state tracking will get messed up.
