block/dirty-bitmap: remove set/reset assertions against enabled bit 

bdrv_set_dirty_bitmap and bdrv_reset_dirty_bitmap are only used as an
internal API by the mirror and migration areas of our code. These
calls modify the bitmap, but do so at the behest of QEMU and not the
guest.

Presently, these bitmaps are always "enabled" anyway, but there's no
reason they have to be.

Modify these internal APIs to drop this assertion.
