bpf: Disallow bpf_obj_new_impl call when bpf_mem_alloc_init fails
In the unlikely event that bpf_global_ma is not correctly initialized,
instead of checking the boolean everytime bpf_obj_new_impl is called,
simply check it while loading the program and return an error if
bpf_global_ma_set is false.
