Subject: [PATCH] ASoC: Intel: atom: Remove redundant check to simplify the code

In the function sst_platform_get_resources(), if platform_get_irq()
failed, the return should not be zero, as the example in
platform.c is
  * int irq = platform_get_irq(pdev, 0)
  * if (irq < 0)
  * return irq;
So remove the redundant check to simplify the code.
