[RFC PATCH 1/2] softmmu/memory: add missing begin/commit callback calls

[Emanuele Giuseppe Esposito <eesposit@redhat.com>]

kvm listeners now need ->commit callback in order to actually send
the ioctl to the hypervisor. Therefore, add missing callers around
address_space_set_flatview(), which in turn calls
address_space_update_topology_pass() which calls ->region_* and
->log_* callbacks.

Using MEMORY_LISTENER_CALL_GLOBAL is a little bit an overkill,
but it is harmless, considering that other listeners that are not
invoked in address_space_update_topology_pass() won't do anything,
since they won't have anything to commit.
