xen/x86: make __direct_remap_pfn_range()'s return value meaningful

From: Olaf Hering <ohering@novell.com>

This change fixes the xc_map_foreign_bulk interface, which would
otherwise cause SIGBUS when pages are gone because -ENOENT is not
returned as expected by the IOCTL_PRIVCMD_MMAPBATCH_V2 ioctl.
