Fix image inflation when offset in BAT is out of image.

Replace whole BAT syncing by flushing only dirty blocks.

Move all the checks outside the main check function in
separate functions

Use WITH_QEMU_LOCK_GUARD for simplier code.

I am happy with this code now.

Stefan, Vova,

can we take this to block-next via one of your trees?
