drm: Handle legacy per-crtc locking with full acquire ctx
drm_mode_cursor_common() was switched to use drm_modeset_(un)lock_crtc()
which uses full aquire ctx. So dropping/reaquiring the lock via
drm_modeset_(un)lock() directly isn't the right thing to do, as lockdep
kindly points out.
The 'FIXME's about sorting out whether vmwgfx *really* needs to lock-all
for cursor updates still apply.
