The `createVlogFile` function creates a new vlog file. The function apart
from …creating a new file, bootstraps it, syncs it to the disk, and mmaps it.
If any of the three operations fail, we will end up with a file on the
disk but the vlog.maxFid will not be updated.
On the next attempt to create the vlog files, we will get a "File
already exists" error. This commit fixes this issue by removing the file
if `createVlogFile` encounters any error.
Fixes DGRAPH-1930
