FreeBSD: Fix regression from kmem_scnprintf() in libzfs

Browse Source 
kmem_scnprintf() is only available in libzpool. Recent buildbot issues
with showing FreeBSD results kept us from seeing this before
97143b9d31 was merged.

The code has been changed to sanitize the output from `kmem_scnprintf()`.
