Use correct format specifier `%d` since args are of type int.

Is it too late for this patch to make 6.0? We are trying to enable -Wformat for clang in 6.0 and this instance of that warning was introduced this development cycle by commit 323aa1f093e6 ("ASoC: SOF: Add a new IPC op for parsing topology manifest"). If I am tracking all my patches correctly, this is the only instance of -Wformat that does not have a patch applied to a maintainer's tree so it would be really unfortunate if we could not sure it on for -rc1.
We could probably route this via the Kbuild tree with an Ack along with the patch that enables -Wformat if it cannot go via Mark's or Takashi's ree.
Cheers, Nathan
