ASoC: wm_adsp: Avoid narrow race condition on compr pointer There is a very small window between then wm_adsp_compr_free gets call and when the DSP is actually powered down. If we get an IRQ from the DSP in this window then the wm_adsp_compr pointer will be NULL. This patch adds a check for this into the IRQ handler to avoid any issues when this happens.
