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'
