Fix regression introduced by r6824
The changes introduced by r6824 broke a subtle, and admittedly obscure, aspect
of the block API. While bdrv_{pread,pwrite} return the number of bytes read
or written upon success, bdrv_{read,write} returns a zero upon success.
When using bdrv_pread for bdrv_read, special care must be taken to handle this
case.
This fixes certain guest images (notably linux-0.2 provided on the qemu
website).
