fix missing return statement. Do not normalize remote paths

[f4hy]

What does this PR do?

Fixes two issues found with #2164 merged yesterday. Local paths worked, but remote directory writing broke in a rebase. My bad.

This was now tested by training and passing --default_root_dir='s3://mybucket/ at training and verified all files write successfully to an s3 bucket. v_num successfully increments on multiple runs. Pointing a tensorboard at the s3 bucket successfully live updates while model is training.
