ASoC: rt5514-spi: Fix potential NULL pointer dereference
commit 060d0bf491874daece47053c4e1fb0489eb867d2 upstream.
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.
