Subject: [PATCH] sched/fair: Cleanup task_util and capacity type

References: bnc#1189999 (Scheduler functional and performance backports)
Patch-mainline: v5.17
Git-commit: ef8df9798d469b7c45c66664550e93469749f1e8

task_util and capacity are comparable unsigned long values. There is no
need for an intermidiate implicit signed cast.
