[ Upstream commit 99e9c5ffbbee0f258a1da4eadf602b943f8c8300 ]
Variable idx is set in the loop, but is never used resulting in dead code. Building with GCC 16, which enables -Werror=unused-but-set-parameter= by default results in build error. This patch removes the idx parameter, since all the callers of the fm10k_unbind_hw_stats_q as 0 as idx anyways.
