[committed] [NFC] Fix riscv_init_cumulative_args for unused arguments

The signature was still using ATTRIBUTE_UNUSED and actually marked one
of the used arguments with ATTRIBUTE_UNUSED.

This patch drops the decorations and instead remove the name of arguments
which are actually unused which is the preferred way to handle this now
when we can.

Bootstrapped.  I didn't have test results on the platform where I
bootstrapped, so no results to compare against.  Given its NFC, I
think we're OK without the regression results.
