Ilya Leoshkevich d5629d1af0 s390/bpf: Fix bpf_arch_text_poke() with new_addr == NULL again ...

commit 6a5abf8cf1 upstream.

Commit 7ded842b35 ("s390/bpf: Fix bpf_plt pointer arithmetic") has
accidentally removed the critical piece of commit c730fce7c7
("s390/bpf: Fix bpf_arch_text_poke() with new_addr == NULL"), causing
intermittent kernel panics in e.g. perf's on_switch() prog to reappear.

Restore the fix and add a comment.
