Variable cfg_val is being assigned but is never used hence it is
redundant and can be removed.
Cleans up clang warning:
warning: variable 'cfg_val' set but not used [-Wunused-but-set-variable]

Actually this made me wonder what is the definition of val_bit.
It seems always 1 in the current code after the commit 964ca8083c02.
Pierre?
I'll look into it, give me a couple of days. I vaguely remember this is
the AES validity bit but I am not sure why it's set with a pcm id, looks
like a mixup.
