Subject: [PATCH] bhyve/vmrun.sh: pass all existing readable disks to
 bhyveload(8)

This is done if the installation mode is not requested or auto-detected.
This is useful when a kernel has to be loaded from multiple disks.
For example from a RAID-Z pool or a ZFS pool with multiple top level
vdevs.
