[PATCH -next] SoC: codecs: wcd938x: fix boolreturn.cocci warning

[Yang Li]

Return statements in functions returning bool should use true/false
instead of 1/0.

Fix the following coccicheck warning:
./sound/soc/codecs/wcd938x.c:1190:9-10: WARNING: return of 0/1 in
function 'wcd938x_volatile_register' with return type bool.
