q6asm: retry asm open in case of session id conflict
The ADSP asm session ids are managed by the kernel driver. It's all right
for native use cases. But for virtualization use cases, there's no way to
synchronize the session ids' status among virtual machines. Playing back
in one virtual machine is probably failed, because the session id may had
been occupied by a use case in another virtual machine.
The patch allowed audio playback stream to try all available session ids
in case of session id conflict error, to support concurrent playback from
multiple virtual machines.
