Modified Files:
        src/external/cddl/osnet/dist/uts/common/fs/zfs: zfs_vfsops.c

Log Message:
Add native vfs_suspend()/vfs_resume() before and after
zfs_suspend_fs()/zfs_resume_fs() and get rid of dead "z_sa_hdl == NULL"
znodes before vfs_resume() to keep the vnode cache consistent.

Live rollback should work now.
