Catch return errors from zpool commands
This fixes a bug that can effect first reboot after install
using Dracut. The Dracut module didn't check the return
value from several calls to z* functions. This resulted in
"Using no pools available as root" on boot if the ZFS module
didn't auto-import the pools. It's most likely to happen on
initial restart after a fresh install & requires juggling in
the Dracut emergency holographic shell to fix.
This patch checks return codes & output from zpool list and
related functions and correctly falls into the explicit zpool
import code branch if the module didn't import the pool at load.
