vfs gd: ignore quota setup errors 

This is a fix to regression in vfs graph driver introduced by
commit 7a1618ced3 ("add quota support to VFS graphdriver").

On some filesystems, vfs fails to init with the following error:

> Error starting daemon: error initializing graphdriver: Failed to mknod
> /go/src/github.com/docker/docker/bundles/test-integration/d6bcf6de610e9/root/vfs/backingFsBlockDev:
> function not implemented

As quota is not essential for vfs, let's ignore (but log as a warning) any error
from quota init.
