ASoC: codecs: wcd938x: fix missing clsh ctrl error handling
commit ed0dd9205bf69593edb495cb4b086dbae96a3f05 upstream.
Allocation of the clash control structure may fail so add the missing
error handling to avoid dereferencing an error pointer.
Fixes: 8d78602aa87a ("ASoC: codecs: wcd938x: add basic driver")
