exec/ram_addr: Return number of dirty pages in cpu_physical_memory_set_dirty_lebitmap()
In preparation for including the number of dirty pages in the
vfio_get_dirty_bitmap() tracepoint, return the number of dirty pages in
cpu_physical_memory_set_dirty_lebitmap() similar to
cpu_physical_memory_sync_dirty_bitmap().
To avoid counting twice when GLOBAL_DIRTY_RATE is enabled, stash the
number of bits set per bitmap quad in a variable (@nbits) and reuse it
there.
