regmap: Fix possible ZERO_SIZE_PTR pointer dereferencing error.
Since we cannot make sure the 'len = pair_size * num_regs' will always
be none zero from the users, and then if 'num_regs' equals to zero by
mistake or other reasons, the kzalloc() will return ZERO_SIZE_PTR, which
equals to ((void *)16).
So this patch fix this with just doing the 'len' zero check before calling
kzalloc().
