exec: fix ram_list dirty map optimization
The ae2810c4bb3b383176e8e1b33931b16c01483aab patch introduced
optimization for ram_list.dirty_memory update. However it can only
work correctly if hpratio is 1 as the @bitmap parameter stores 1 bits
per system page size (may vary, 4K or 64K on PPC64) and
ram_list.dirty_memory stores 1 bit per TARGET_PAGE_SIZE
(which is hardcoded to 4K).
This fixes hpratio!=1 case to fall back to the slow path.
