Brian Behlendorf 455c36156c ZTS: refreserv/refreserv_raidz improvements
Several small changes intended to make this test reliable.

- Leave the default compression enabled for the pool and switch
  to using /dev/urandom as the data source.  Functionally this
  shouldn't impact the test but it's preferable to test with
  the pool defaults when possible.

- Verify the device is created and removed as required.  Switch
  to a unique volume name for a more clarity in the logs.

- Use the ZVOL_DEVDIR to specify the device path.

- Speed up the test by creating the pool with an ashift=12 and
  testing 4K, 8K, 128K volblocksizes.
