xen: Don't pass MemoryListener around by value
Coverity points out (CID 1513106, 1513107) that MemoryListener is a
192 byte struct which we are passing around by value. Switch to
passing a const pointer into xen_register_ioreq() and then to
xen_do_ioreq_register(). We can also make the file-scope
MemoryListener variables const, since nothing changes them.
