ZTS: devices_001_pos and devices_002_neg
Update the devices_001_pos and devices_002_neg test cases such that the special block device file created is backed by a ZFS volume. Specifying a specific device allows the major and minor numbers to be easily determined. Furthermore, this avoids the potentially dangerous behavior of opening the first block device we happen to find under /dev/. Reviewed-by: Ryan Moeller <ryan@ixsystems.com> Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #9773
