[PATCH - Multiple plugins 2/4] jack: Fix leaks when jack_set_hw_constraint() fails

[Andre Guedes <andre.guedes@intel.com>]

If jack_set_hw_constraint() returns error, we leak the 'jack' object and
all the resources referenced by it. This patch fixes the issue by
calling snd_pcm_jack_free() before returning.
