Alan Somers 0b294a386d Fix zfsd with the device_removal pool feature.
Previously zfsd would crash in the presence of a pool with a
top-level-vdev that had previously been removed.  The crash happened
because the configuration nvlist of such a TLV contains an empty
ZPOOL_CONFIG_CHILDREN array, which led to a pop_front from an empty
list, which has undefined behavior.

The crash only happened in stable/14 and later, probably do to
differences in libcxx, but the change should be MFCed anyway.
