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

[ Upstream commit 7cb50f6c9f ]

Introduced a stupid bug in commit 782bfd03c3 ("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.
