Subject: [PATCH] softirq: Adjust comment for CONFIG_PREEMPT_RT in #else

The #ifdef CONFIG_PREEMPT_RT #else statement had a comment
that made me think the code below #else statement was RT code.
After reading the code closer I realized it was not RT code.
Adjust comment to !RT to helper future readers of the code.

Fixes: 8b1c04acad08 ("softirq: Make softirq control and processing RT aware")
