8898 creating fs with checksum=skein on the boot pools fails ungracefully

illumos/illumos-gate@9fa2266d9a78b8366e1cd2d5f050e8b5e37d558c

https://www.illumos.org/issues/8898:
# zfs create -o checksum=skein rpool/test
internal error: Result too large
Abort (core dumped)

Not a big deal per se, but should be handled correctly.
