media: coda: Fix missing put_device() call in coda_get_vdoa_data

BugLink: https://bugs.launchpad.net/bugs/1969110
[ Upstream commit ca85d271531a1e1c86f24b892f57b7d0a3ddb5a6 ]

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.
