Marc-André Lureau ba43d28916 hda: do not mix output and input stream states, RHBZ #740493
Windows 7 may use the same stream number for input and output.
Current code will confuse streams.

Changes since v1:
- keep running_compat[] for migration version 1
- add running_real[] for migration version 2
