Issuing the READ CAPACITY(10) command in the guest will cause QEMU to update its knowledge of the maximum accessible LBA in the disk. The recorded maximum LBA will be wrong if the disk is bigger than 1TB, because ldl_be_p returns a signed int. When this is fixed, a latent bug will be unmasked. If the READ CAPACITY(10) command reported an overflow (0xFFFFFFFF), we must not overwrite the previously-known maximum accessible LBA, or the guest will fail to access the disk above the first 2TB.
