drm/msm: Fix dirtyfb refcounting
refcount_t complains about 0->1 transitions, which isn't *quite* what we
wanted. So use dirtyfb==1 to mean that the fb is not connected to any
output that requires dirtyfb flushing, so that we can keep the underflow
and overflow checking.
Fixes: 9e4dde28e9cd ("drm/msm: Avoid dirtyfb stalls on video mode displays (v2)")
