[Xen-devel] [PATCH] xen/arm: arch_domain_create: don't return 0 when alloc_xenheap_pages has failed



The previous call before alloc_xenheap_pages reset rc to 0 if it success.
If the latter fails, arch_domain_create will return 0 and Xen will consider
the domain as valid. Move rc initialization later.
