Subject: drm/hdlcd: Don't call drm_crtc_vblank_off on unbind
Git-commit: ba931cfd078778879ec51c6483577eb4645b70dd
Patch-mainline: v5.9-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322

This is already taken care of by drm_atomic_helper_shutdown(), and
in that case only for the CRTC which are actually on.

Only tricky bit here is that we kill the interrupt handling before we
shut down crtc, so need to reorder that.
