Description

An uninitialized 'err' variable introduced by #1647 means that, depending on the stack layout, zfs(1M) may be unable to destroy datasets unless the -R or -r options are given.

in zfs_do_destroy, if the uninitialized err is non-0, and it is used uninitialized (cb_doclones is false), destroy will always fail and never run
zfs_destroy_snaps_nvl, making snapshots impossible to destroy.
