vm/qemu.go: fix nil-ptr-deref in ctor
os.Stat() may return (nil, err) if it fails to open a file.
So, the code below wrongly validates st as it will be always nil
if err != nil, causing nil pointer dereference in st.Size().
```
if st, err := os.Stat(inst.image); err != nil && st.Size() == 0 {
```
To fix this, this patch allows st.Size() only if err == nil.
