ASoC: SDCA: Add allocation failure check for Entity name

Browse source 
Currently find_sdca_entity_iot() can allocate a string for the
Entity name but it doesn't check if that allocation succeeded.
Add the missing NULL check after the allocation.

Fixes: 48fa77af2f ("ASoC: SDCA: Add terminal type into input/output widget name")
