spi: Fix possible ZERO_SIZE_PTR pointer dereferencing error.
Since we cannot make sure the 'n' will always be none zero here, and
then if either equal to zero, the kzalloc() will return ZERO_SIZE_PTR,
which equals to ((void *)16).
So this patch fix this with just doing the zero check before calling
kzalloc().
