[PATCH bpf-next v1 2/7] bpf: Be consistent between {acquire,find,release}_lock_state

[Kumar Kartikeya Dwivedi <memxor@gmail.com>]

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.
