This reverts commit cdef3abb25984c369571626b38f97f92a0a2fd15.

The bug should be fixed by now [0]. The reproducer doesn't cause any
issues in my tests.

AFAICT this has an affect on EFI disks which after this revert will be
528k and not 1M. Similar as if we would store it as a .raw file.

I don't know about other tiny volume datasets. The TPM is 4M already.
