Reproducible panic playing with zpool remove in FreeBSD 11.2-RELEASE.

[Maurizio Vairani]

Hi,

boot the 11.2-RELEASE installation media in the <Live CD>.
Insert an USB memory stick, suppose it is /dev/da5.
# gpart create -s GPT da5
# gpart add -t freebsd-zfs -a 1m -s 1g da5
# gpart add -t freebsd-zfs -a 1m -s 1g da5
# zpool create -O mountpoint=/tmp/ztest ztest da5p1 da5p2
# cp /bin/* /tmp/ztest
# zpool remove ztest da5p1
# rm /tmp/ztest/*
PANIC !

I have tested the above commands with 3 different PC and only in one I 
can see the panic screen, the other PC reboot after the panic.
