Ryan Moeller 4a2e9811e9 FreeBSD: Avoid spurious EINTR in zvol_cdev_open
zvol_first_open can fail with EINTR if spa_namespace_lock is not held
and cannot be taken without waiting.

Apply the same logic that was done for zvol_geom_open to take
spa_namespace_lock if not already held on first open in zvol_cdev_open.
