If issued right after link down, "blockdev --rereadpt" will be stuck for a while and then return normally. Although the underlying capacity and partition table are not correctly updated. And it means that userspace can't detect the error at all.
Fix this by propargating the error of "read capacity" command through the stack, so that the ioctl could fail with -EIO.
