media: mtk-vcodec: Release device nodes in mtk_vcodec_init_enc_pm()

Browse source

of_parse_phandle() returns the device node with refcount incremented.
There are two nodes that are used temporary in mtk_vcodec_init_enc_pm(),
but their refcounts are not decremented.

The patch adds one of_node_put() and fixes returning error codes.
