sched/psi: Fix psi_seq initialization
[ Upstream commit 99b773d720aeea1ef2170dce5fcfa80649e26b78 ]
With the seqcount moved out of the group into a global psi_seq,
re-initializing the seqcount on group creation is causing seqcount
corruption.
Fixes: 570c8efd5eb7 ("sched/psi: Optimize psi_group_change() cpu_clock() usage")
