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.
