Subject: [PATCH] ath9k: remove unused array firstep_table

From: Colin Ian King <colin.king@...onical.com>

Array firstep_table is being assigned but is never used
hence it is redundant and can be removed.

Cleans up clang warning:
warning: 'firstep_table' defined but not used [-Wunused-const-variable=]
