PSA_MAC_FINAL_SIZE: we don't use key_bits at the moment

Browse Source 
None of the currently defined MAC algorithms have a MAC size that
depends on the key size, so the key_bits parameter is unused. The
key_type parameter may be unused on an implementation where there is
no block cipher MAC. Declare the key_type and key_bits parameters as
used so that callers who define a variable just for this don't risk
getting "unused variable" warnings.
