  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.
