ASoC: SOF: imx: remove error checks on NULL ipc

imx_dsp_get_data() can return NULL, but the value is not checked
before being usd, leading to static analysis warnings.

sound/soc/sof/imx/imx8.c:85:32: error: dereference of NULL ‘0’
[CWE-476] [-Werror=analyzer-null-dereference]

   85 |         spin_lock_irqsave(&priv->sdev->ipc_lock, flags);
      |                            ~~~~^~~~~~

It appears this is not really a possible problem, so remove those checks.
