git-submodule: Avoid 'fatal: cannot describe' message

When "git submodule status" command tries to show the name of the
submodule HEAD revision more descriptively, but the submodule
repository lacked a suitable tag to do so, it leaked "fatal: cannot
describe" message to the UI.  Squelch it by using '--always'.
