Subject: [PATCH] xen: ignore live parameter from xen-save-devices-state

The final step of xl migrate|save for an HVM domU is saving the state of
qemu. This also involves releasing all block devices. While releasing
backends ought to be a separate step, such functionality is not
implemented.

Unfortunately, releasing the block devices depends on the optional
'live' option. This breaks offline migration with 'virsh migrate domU
dom0' because the sending side does not release the disks, as a result
the receiving side can not properly claim write access to the disks.

As a minimal fix, remove the dependency on the 'live' option. Upstream
may fix this in a different way, like removing the newly added 'live'
parameter entirely.

Fixes: 5d6c599fe1 ("migration, xen: Fix block image lock issue on live migration")
