Sector-based blk_read() should die; switch to byte-based
blk_pread() instead.

Not compile tested - I'm not sure what else I'd need in my environment
to actually test this one.  I have:
Fedora 23, dnf builddep qemu
./configure --enable-kvm --enable-system --disable-user --target-list=x86_64-softmmu,ppc64-softmmu --enable-debug
