media: mtk-vcodec: add missing put_device() call in mtk_vcodec_init_dec_pm() 

[ Upstream commit 5d4fa2c50125c9cda9e380d89268757cc5fa743d ]

if of_find_device_by_node() succeed, mtk_vcodec_init_dec_pm() doesn't have
a corresponding put_device(). Thus add jump target to fix the exception
handling for this function implementation.
