ALSA: firewire-digi00x: simplify error path to begin streaming session
This commit is a part of preparation to perform allocation/release
of isochronous resources in pcm.hw_params/hw_free callbacks.
The caller of begin_session() calls finish_session() in its error path,
thus no need to call finish_session() in error path of begin_session().
This commit simplifies error path of begin_session().
