ASoC: cache: Fix possible ZERO_SIZE_PTR pointer dereferencing error.

Since we cannot make sure the 'reg_size' will always be none zero here,
and then if 'reg_size' equals to zero, the kzalloc() will return ZERO_SIZE_PTR,
which equals to ((void *)16).

So this patch fix this with just doing the 'reg_size' zero check before calling
kzalloc().
