[PATCH v3] sched/psi: Fix !CONFIG_PSI stub parameter types for psi_enqueue/dequeue()

[Zhan Xusheng]

commit 1a6151017ee5 ("sched: psi: pass enqueue/dequeue flags to psi
callbacks directly") changed psi_enqueue() and psi_dequeue() to take
'int flags' instead of 'bool migrate', but missed updating the
!CONFIG_PSI stubs in kernel/sched/stats.h, which still take
'bool migrate'.

Keep the stub prototypes in sync with the real functions so both build
variants share the same signature. No functional change.

v3:
 - Reword the changelog: state the consistency rationale and use
   "No functional change" instead of "silent and harmless in practice"
 - No code change vs v2 (one-line stub signature fix)
v2: https://lore.kernel.org/all/20260512022308.4141509-1-zhanxusheng@xxxxxxxxxx/
