ALSA: pcm: oss: Use struct_size() helper
Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes, in particular in the
context in which this code is being used.
So, replace the following form:
sizeof(struct rate_priv) + src_format->channels * sizeof(struct rate_channel)
with:
struct_size(data, channels, src_format->channels)
This code was detected with the help of Coccinelle.
