block/vhdx: Support vhdx image only with 512 bytes logical sector size

block/vhdx uses qemu block layer where sector size is always 512 bytes.
This may have issues  with 4K logical sector sized vhdx image.

For e.g qemu-img convert on such images fails with following assert:

$qemu-img convert -f vhdx -O raw 4KTest1.vhdx test.raw
qemu-img: util/iov.c:388: qiov_slice: Assertion `offset + len <=
qiov->size' failed.
Aborted

This patch adds an check to return ENOTSUP for vhdx images which
have logical sector size other than 512 bytes.
