[PATCH] sched_ext: Fix incorrect SCX_PICK_IDLE_CPU_* flag prefix in kernel-doc

Newsgroups dev.linux.lists.sched-ext,org.kernel.vger.linux-kernel
Message-ID <[email protected]>
From: Liang Luo <[email protected]>

The flags passed to the pick-idle kfuncs are values from the
scx_pick_idle_cpu_flags enum, whose members are prefixed
SCX_PICK_IDLE_ (SCX_PICK_IDLE_CORE, SCX_PICK_IDLE_IN_NODE).

Three kernel-doc comments in idle.c erroneously used
%SCX_PICK_IDLE_CPU_* which does not correspond to any defined flag
name, while the adjacent scx_bpf_pick_idle_cpu_node() correctly
documents %SCX_PICK_IDLE_*.

Fix the three occurrences to use the correct SCX_PICK_IDLE_* prefix.
