Markus Armbruster 37aa7a0e2f xen-hvm: Clean up xen_ram_alloc() error handling
xen_ram_alloc() dies with hw_error() on error, even though its caller
ram_block_add() handles errors just fine.  Add an Error **errp
parameter and use it.

Leave case RUN_STATE_INMIGRATE alone, because that looks like some
kind of warning.
