Both acquire_lock_state and release_lock_state take the bpf_func_state
as a parameter, while find_lock_state does not. Future patches will end
up requiring operating on non-cur_func(env) bpf_func_state (for
resilient locks), hence just make the prototype consistent and take
bpf_func_state directly.
