Revert "Check reauth status before attempting upload"

This reverts commit 70b1a7209cd67d82b50785d7ffa89a3bae895649.

Reason for revert: A test introduced by this change causes CI failures.
https://ci.chromium.org/ui/p/chromium/builders/ci/Linux%20ChromiumOS%20MSan%20Tests
The faulty test is OneDriveUploadHandlerTest
FailToStartUploadDueToReauthenticationRequired.

Original change's description:
> Check reauth status before attempting upload
>
> Better to first check if we already are in the reauth required state,
> because then we know we will fail to upload.
>
> Add a new UMA to indicate we've bailed out at this early stage, so
> we can count these directly, rather than try to get them out of
> ODFS metrics for GetMetadata, CreateFile etc. which upload will
> eventually cause.
>
> Bug: none
