Fix savevm after BDRV_FILE size enforcement

 
 We now enforce that you cannot write beyond the end of a non-growable file.
 qcow2 files are not growable but we rely on them being growable to do
 savevm/loadvm.  Temporarily allow them to be growable by introducing a new
 API specifically for savevm read/write operations.
