ASoC: rt5677: Add missing null check for failed allocation of rt5677_dsp
The allocation of rt5677_dsp can potentially fail and return null, so add
a null check and return -ENOMEM on a memory allocation failure.
Addresses-Coverity: ("Dereference null return")
Fixes: a0e0d135427c ("ASoC: rt5677: Add a PCM device for streaming hotword via SPI")
