commit bcf493428840 ("netfilter: ebtables: Fix extension lookup with
identical name") added a second lookup in case the extension that was
found during the first lookup matched another extension with the same
name, but didn't release the reference on the incorrect module.

Fixes: bcf493428840 ("netfilter: ebtables: Fix extension lookup with identical name")
