[PATCH] generic/730: skip on ext4 when dax is enabled

[Disha Goel <disgoel@linux.ibm.com>]

The generic/730 test utilizes the scsi_debug driver to create a
synthetic SCSI block device for testing. However, scsi_debug does
not support DAX capabilities.

When xfstests is configured with DAX mount options, ext4 strictly
validates the block device during the mount phase. This results
in a mount failure:
  EXT4-fs (sdc): DAX unsupported by block device.

Skip this test for ext4 when the 'dax' mount option is present to
avoid false failures.
