[fstests PATCH 2/2] generic/347: dm-thin lacks DAX support

[Ross Zwisler <ross.zwisler@linux.intel.com>]

generic/347 currently fails when run in cojunction with the DAX mount
option:

This is expected because the dm-thin target currently lacks DAX support.

Just skip this test if we are using DAX.
