libxc: do not align/lock buffers which do not need it
On restore:
region_mfn is passed to xc_map_foreign_range and
xc_map_foreign_bulk. In both cases the buffer is accessed from the
ioctl handler in the kernel and not from any hypercall. Therefore
normal copy_{to,from}_user handling in the kernel will cope with any
faulting access.
p2m_batch is passed to xc_domain_memory_populate_physmap which takes
care of bouncing the buffer already.
On save:
pfn_type is passed to xc_map_foreign_bulk which does not need locking
as per region_mfn above.
