Alexander Lvov fa7cad4aee block: vhdx: enable bounds check in sync I/O worker ...

VhdxSync::submit_data_operation() passed every read/write straight to
the underlying Vhdx without checking the request against the virtual
disk's logical size. A request that started inside the image but
extended past its end (or an offset past the end entirely) was passed
through unchecked, silently reading/writing out of the intended
bounds.

Call AsyncIoOperation::validate_bounds() from submit_data_operation()
before dispatching the operation, the same way the VHD sync worker
does. The check rejects any request whose offset + length exceeds the
logical size.
