Ryan Moeller 020545a95d FreeBSD: Fix zvol_*_open() locking ... These are the changes for FreeBSD corresponding to the changes made for Linux in #12863, see that PR for details. Changes from #12863 are applied for zvol_geom_open and zvol_cdev_open on FreeBSD. This also adds a check for the zvol dying which we had in zvol_geom_open but was missing in zvol_cdev_open. The check causes the open to fail early with ENXIO when we are in the middle of changing volmode.
