When a unit has credentials, stopping the service unmounts the credentials directory. On shutdown, stopping the service and the corresponding mount unit may be done mostly simultaneously, and if we invoke umount command soon after umount() being called on stopping the service, the mount unit will fail. This makes Mount.invalidated_state flag set when umount() is called for a path, and re-read /proc/self/mouninfo before invoking umount command if the flag is set. Fixes #25527. Replaces #26959.
