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

[Biren Pandya <birenpandya@gmail.com>]

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.

Fixes: ca50c197bd96 ("[media] v4l: fwnode: Support generic fwnode for parsing standardised properties")
