[PATCH v2 1/2] bpf: Replace sort_r_nonatomic() with sort_r() in check_dup_ids()

[Kuan-Wei Chiu <visitorckw@gmail.com>]

bpf_kprobe_multi_link_attach() in the same file has been using sort_r()
under the exact same limit (1U << 20) for 4 years without issues.
Switch check_dup_ids() from sort_r_nonatomic() to sort_r() to match it.

This removes the last in-tree user of sort_r_nonatomic(), allowing the
unused _nonatomic() sort variants to be dropped from the core library.
