storage: fs: Don't attempt directory creation if it already exists

The current code attempts to handle this, but it only catches mkdir
failing with EEXIST. However if say trying to build /tmp for an
unprivileged qemu:///session, mkdir will fail with EPERM.

Rather than catch any errors, just don't attempt mkdir if the directory
already exists.
