Alexander Lvov e0801bda3b block: vhd: fix incomplete bounds check in sync I/O worker ...

The sync I/O worker only checked that the operation offset did
not start past the end of the virtual disk (offset >= size) -
did not verify that the operation end (offset + len) stays
within bounds.

A read or write that started inside the image but extended
beyond the logical size was silently passed to the raw backend.

The async io_uring worker already had the correct check
(offset + len > size with overflow protection). I extracted it
into a shared helper in worker/common.rs and reused inside the
sync path to eliminate duplication and close the gap.

Fixes #8311
