drm/sun4i: add missing put_device() call in sun8i_r40_tcon_tv_set_mux() 

[ Upstream commit 07b5b12d97 ]

If sun8i_r40_tcon_tv_set_mux() succeed, sun8i_r40_tcon_tv_set_mux()
doesn't have a corresponding put_device(). Thus add put_device()
to fix the exception handling for this function implementation.
