[OE-core] [PATCH 1/1] metadata.py: return info after fallback methods

[Chen Qi]

If python3 git module is not installed, we fall back to some git
command to get info. A previous commit (b8d22ed6) accidently deleted
the return statement, causing errors like below.

  Exception: UnboundLocalError: local variable 'InvalidGitRepositoryError' referenced before assignment
