qed: Make qiov match request size until backing file EOF
If a QED image has a shorter backing file and a read request to unallocated clusters goes across EOF of the backing file, the backing file sees a shortened request and the rest is filled with zeros. However, the original too long qiov was used with the shortened request. This patch makes the qiov size match the request size, avoiding a potential buffer overflow in raw-posix.
