memory: fix usage of find_next_bit and find_next_zero_bit
The last two arguments to these functions are the last and first bit to check relative to the base. The code was using incorrectly the first bit and the number of bits. Fix this in cpu_physical_memory_get_dirty and cpu_physical_memory_all_dirty. This requires a few changes in the iteration; change the code in cpu_physical_memory_set_dirty_range to match.
