[Libguestfs] [PATCH] RHEV: Only mark the first disk as bootable

[Matthew Booth]

RHEV will fail to start a guest with more than one VirtIO disk marked as
bootable. The previous behaviour of V2V simply marked all disks as bootable,
intending to follow the behaviour of libvirt's qemu driver. However, libvirt's
qemu driver actually only marks the first disk specified in the domain XML
(which may or may not be Xda) as bootable. This change updates the RHEV output
to follow this.

Fixes RHBZ#595619
