Eliminate N+1 queries in LFS file locks checks during a pushsh-optimize-locks-check-ce
This significantly improves performance when a user pushes many references.
project.path_locks.any? doesn't cache the output and runs `SELECT 1 AS one
FROM "path_locks" WHERE project_id = N` each time. When there are thousands
of refs being pushed, this can time out the unicorn worker.
