pack SD_ASYM_PACKING into sched_use_asym_prio

Instead of saying `pack` you could say "Check the SD_ASYM_PACKING flag
in sched_use_asym_prio()"

I'd the changelog as follows:

"sched_use_asym_prio() checks whether CPU priorities should be used. It
makes sense to check for the SD_ASYM_PACKING() inside the function.
Since both sched_asym() and sched_group_asym() use sched_use_asym_prio(),
remove the now superfluous checks for the flag in various places"
