xen/arm: don't ignore return errors from set_phys_to_machine
commit 36bf1dfb8b266e089afa9b7b984217f17027bf35 upstream.
set_phys_to_machine can fail due to lack of memory, see the kzalloc call
in arch/arm/xen/p2m.c:__set_phys_to_machine_multi.
Don't ignore the potential return error in set_foreign_p2m_mapping,
returning it to the caller instead.
This is part of XSA-361.
