[PATCH v5 01/11] xen: make xen loader callable multiple times

The loader for xen paravirtualized environment isn't callable multiple times as it won't free any memory in case of failure. Call grub_relocator_unload() as other modules do it before allocating a new relocator or when unloading the module. Signed-off-by: Juergen Gross Reviewed-by: Daniel Kiper
