sched: Fix sync wakeups again

Browse Source 
The sync argument rename to introduce WF_* broke stuff by missing a
local alias for an argument in __wake_up_common, fix it by using
the more descriptive wake_flags name.

This restores WF_SYNC propagation, which fixes wake_affine()
behaviour, which fixes pipe-test.
