zfs tests fails, pool related

[Manuel Bouyer <bouyer%antioche.eu.org@localhost>]

Hello
http://www-soc.lip6.fr/~bouyer/NetBSD-tests/xen/HEAD/amd64/201711142340Z_atf.html#failed-tcs-summary

all zfs tests fails, with:
panic: kernel diagnostic assertion "!(flags & PR_NOWAIT) != !(flags & PR_WAITOK)" failed: file "/usr/src/lib/librump/../../sys/rump/../kern/subr_pool.c", line 2229 

I guess this is related to recent pool changes, but looks like a bug
in parameters to pool_cache_get_paddr() in zfs ...
