of: property: fw_devlink: Fix stupid bug in remote-endpoint parsing

Introduced a stupid bug in commit 782bfd03c3ae ("of: property: Improve
finding the supplier of a remote-endpoint property") due to a last minute
incorrect edit of "index !=0" into "!index". This patch fixes it to be
"index > 0" to match the comment right next to it.
