From: Jason Xing I received a kernel-test-bot report[1] that shows the [-Wunused-but-set-variable] warning. Since the previous commit[2] I made gives users an option to turn on and off the CONFIG_RFS_ACCEL, the issue then can be discovered and reproduced. Move the @i into the protection of CONFIG_RFS_ACCEL.
