Summary

In the past the zilog was initialized in the zvol_first_open (https://svnweb.freebsd.org/base/stable/12/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/zvol.c?revision=365689&view=markup#l842).
While the openzfs upgrade this was dropped.
This cause an page fault in the zvol_cdev_open function while accessing the ZVOL.
