ASoC: rt5514-spi: Fix potential NULL pointer dereference
There is a potential NULL pointer dereference in case devm_kzalloc()
fails and returns NULL.
Fix this by adding a NULL check on rt5514_dsp.
This issue was detected with the help of Coccinelle.
Fixes: 6eebf35b0e4a ("ASoC: rt5514: add rt5514 SPI driver")
