bpf: Use architecture provided res_smp_cond_load_acquire
In v2 of rqspinlock [0], we fixed potential problems with WFE usage in
arm64 to fallback to a version copied from Ankur's series [1]. This
logic was moved into arch-specific headers in v3 [2].
However, we missed using the arch-provided res_smp_cond_load_acquire
in commit ebababc ("rqspinlock: Hardcode cond_acquire loops for arm64")
due to a rebasing mistake between v2 and v3 of the rqspinlock series.
Fix the typo to fallback to the arm64 definition as we did in v2.
