[PATCH 2/5] overlay/014: fix test with inodes index enabled

[Amir Goldstein <amir73il@gmail.com>]

When overlayfs is configured with CONFIG_OVERLAY_FS_INDEX=y,
workdir from previous overlay mount cannot be reused in a new
overlay mount that uses a different upper dir.

Fix the test to use a different workdir when mounting with a
different upper dir.

This change has not effect on older kernels and overlay
configured without CONFIG_OVERLAY_FS_INDEX.
