[PATCH v2] media: v4l2-core: Fix memory leak in v4l2_fwnode_parse_link

[Biren Pandya]

In v4l2_fwnode_parse_link(), the remote endpoint fwnode reference is
acquired using fwnode_graph_get_remote_endpoint(). This reference is
properly released in the error paths, but it is leaked on the success
path.

Add the missing fwnode_handle_put() before returning 0 to prevent the
reference leak.

Changes in v2:
- Resend because the v1 patch was lost in transit and did not appear on lore.kernel.org, causing CI to fail looking for the message ID. No code changes.
