Subject: [PATCH 1/5] sched/psi: Make psi stubs consistent for !CONFIG_PSI

commit 1a6151017ee5 ("sched: psi: pass enqueue/dequeue flags to psi
callbacks directly") modified the psi_enqueue() and psi_dequeue()
functions to take the complete enqueue/dequeue flags but left the stubs
for !CONFIG_PSI unaltered.

Modify the stubs to also accept the flags argument to keep it consistent
with CONFIG_PSI.
