Subject: [PATCH v2 2/2] sched/fair: Fix task_fits_capacity() capacity type

capacity is an unsigned long value, compared with a task utilization which
is unsigned long as well. There's no need for an intermediate implicit
long cast.

Fixes: 3b1baa6496e6 ("sched/fair: Add 'group_misfit_task' load-balance type")
