ram_addr: tweaks to xen_modified_memory

Invoke xen_modified_memory from cpu_physical_memory_set_dirty_range_nocode;
it is akin to DIRTY_MEMORY_MIGRATION, so set it together with that bitmap.
The remaining call from invalidate_and_set_dirty's "else" branch will go
away soon.

Second, fix the second argument to the function in the
cpu_physical_memory_set_dirty_lebitmap call site.  That function is only used
by KVM, but it is better to be clean anyway.
