Subject: [PATCH] fix org repo creation being limited by user limits (#34030)

fixes an issue where user is unable to create new repository in
organization via UI if repository limits are in place and user has
exhausted them for their own namespace.

closes: https://github.com/go-gitea/gitea/issues/15504
