Ammar Faizi b6094744e2 ASoC: SOF: Intel: Fix NULL ptr dereference when ENOMEM
commit b7fb0ae090 upstream.

Do not call snd_dma_free_pages() when snd_dma_alloc_pages() returns
-ENOMEM because it leads to a NULL pointer dereference bug.

The dmesg says:

  [ T1387] sof-audio-pci-intel-tgl 0000:00:1f.3: error: memory alloc failed: -12
