[PATCH] media: coda: Fix missing put_device() call in coda_get_vdoa_data

[Miaoqian Lin]

The reference taken by 'of_find_device_by_node()' must be released when
not needed anymore.
Add the corresponding 'put_device()' in the error handling path.

Fixes: e7f3c5481035 ("[media] coda: use VDOA for un-tiling custom macroblock format")
