OMAP3/4: l3: fix omap3_l3_probe error path

l3_smx:
- Add missing free_irq and remove an empty goto label.

l3_noc:
- If kzalloc fails driver shouldn't continue with a NULL pointer.
- Add missing free_irq and remove empty goto labels.
- Safe to assume that if we reached the end point of execution
  without errors, then return value is 0, so replacing instead
  another goto.
