ASoC: SDCA: Add allocation failure check for Entity name
[ Upstream commit 27990181031fdcdbe0f7c46011f6404e5d116386 ]
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: 48fa77af2f4a ("ASoC: SDCA: Add terminal type into input/output widget name")
