[PATCH] Stop hiding the error message within 'git submodule add'

[John Szakmeister <john@szakmeister.net>]

git-submodule.sh was incorrectly assuming that the only reason
'git add --dry-run' would fail was due to ignored paths.  However,
when trying add a submodule inside of another, the original error
message was being lost, and leaves a user confused.  Simply
re-run 'git add --dry-run' and allow the error message emitted.
