block: Fix integer promotion error in bdrv_getlength()
Back in 2015, we attempted to fix error reporting for images that claimed to have more than INT64_MAX/512 sectors, but due to the type promotions caused by BDRV_SECTOR_SIZE being unsigned, this inadvertently forces all negative ret values to be slammed into -EFBIG rather than the original error. While we're at it, we can avoid the confusing ?: by spelling the logic more directly.
