vpc: fix return value check for blk_pwrite
bdrv_pwrite_sync used to return zero or negative error, while blk_pwrite returns
the number of written bytes when successful. This caused VPC image creation
to fail spectacularly: it wrote the first 512 bytes, and then exited immediately
because of the non-zero answer from blk_pwrite. But the truly spectacular part
is that it returns a positive value (the 512 that blk_pwrite returned) causing
everyone to believe that it succeeded.
This fixes qemu-iotests with vpc format.
