ASoC: codec: sma1307: Fix memory corruption in sma1307_setting_loaded()

In the Linux kernel, the following vulnerability has been resolved:

ASoC: codec: sma1307: Fix memory corruption in sma1307_setting_loaded()

The sma1307->set.header_size is how many integers are in the header
(there are 8 of them) but instead of allocating space of 8 integers
we allocate 8 bytes.  This leads to memory corruption when we copy data
it on the next line:

        memcpy(sma1307->set.header, data,
               sma1307->set.header_size * sizeof(int));

Also since we're immediately copying over the memory in ->set.header,
there is no need to zero it in the allocator.  Use devm_kmalloc_array()
to allocate the memory instead.
