xen: add return value to set_phys_to_machine()
set_phys_to_machine() can return false on failure, which means a memory
allocation failure for the p2m structure. It can only fail if setting
the mfn for a pfn in previously unused address space. It is guaranteed
to succeed if you're setting a mapping to INVALID_P2M_ENTRY or updating
the mfn for an existing pfn.
