[PATCH] git-submodule: Error messages from 'git describe' shouldn't end up on the terminal

As of now a failure to locate the closest tag to a commit (e.g because there is
no tag in the repository) is handled explicitly by displaying an 'undefined' tag
error message. However when git describe fails it will still display an
undesirable  "fatal: cannot describe SHA1" message. This patch hides that
message as git-submodule has an alternative and explicit error handling method
in place for this situation
