riscv: drop cpufeature_apply_feature tracking variable
From: Heiko Stuebner <heiko@...> Date: Wed, 18 May 2022 13:21:55 +0200
Commit-Message
The variable was tracking which feature patches got applied but that information was never actually used - and thus resulted in a warning as well. Drop the variable. Reported-by: kernel test robot <lkp@...> Signed-off-by: Heiko Stuebner <heiko@...>
