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

Browse Source 
[ Upstream commit 27c3943683f74e35e1d390ceb2e3639eff616ad6 ]

mtk_vcodec_release_dec_pm() will be called in two places:

a. mtk_vcodec_init_dec_pm() succeed while mtk_vcodec_probe() return error.
b. mtk_vcodec_dec_remove().

In both cases put_device() call is needed, since of_find_device_by_node()
was called in mtk_vcodec_init_dec_pm() previously.

Thus add put_devices() call in mtk_vcodec_release_dec_pm()
