block: fix SG_[GS]ET_RESERVED_SIZE ioctl when max_sectors is huge
SG_GET_RESERVED_SIZE and SG_SET_RESERVED_SIZE ioctls access a reserved
buffer in bytes as int type. The value needs to be capped at the request
queue's max_sectors. But integer overflow is not correctly handled in
the calculation when converting max_sectors from sectors to bytes.
