drm/modeset-lock: Take the modeset BKL for legacy drivers

This fell off in the conversion in

    drm: Replace drm_modeset_lock/unlock_all with DRM_MODESET_LOCK_ALL_* helpers

but it's caught by the drm_warn_on_modeset_not_all_locked() that the
legacy modeset code uses. Since this is the bkl and it's unclear
what's all protected, play it safe and grab it again for legacy
drivers.

Unfortunately this means we need to sprinkle a few more #includes
around.

Also we need to add the drm_device as a parameter to the _END macro.

Finally remove the mute_lock() from setcrtc, since that's now done by
the macro.
