spapr: Provide an error message when migration fails due to htab_shift mismatch
Include an error message when migration fails due to mismatch in htab_shift values at source and target. This should provide a bit more verbose message in addition to the current migration failure message that reads like: qemu-system-ppc64: error while loading state for instance 0x0 of device 'spapr/htab' After this patch, the failure message will look like this: qemu-system-ppc64: htab_shift mismatch: source 29 target 24 qemu-system-ppc64: error while loading state for instance 0x0 of device 'spapr/htab' Signed-off-by: Bharata B Rao <bharata@linux.vnet.ibm.com> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
