Hi Dave, Daniel,

drm/atomic: use connector references (v3)
Take a reference when setting a crtc on a connecter,
also take one when duplicating if a crtc is set,
and drop one on destroy if a crtc is set.
v2: take Daniel Stone's advice and simplify the
ref/unref dances, also take care of NULL as connector
to state reset.
v3: remove need for connector NULL check.
