Ryan Moeller aaeffd09bf zvol_os: Fix handling of zvol private data
zvol private data is supposed to be nulled by zvol_clear_private before
zvol_free is called as an indicator that the zvol is going away.

Implement zvol_clear_private for volmode=dev.

Assert that zvol_clear_private has been called before zvol_free.

Check that zvol_clear_private has not been called when updating
volsize.  If it has, fail with ENXIO.
