Michael Holzheu 88aeca15d6 s390/bpf: fix bpf frame pointer setup
Currently the bpf frame pointer is set to the old r15. This is
wrong because of packed stack. Fix this and adjust the frame pointer
to respect packed stack. This now generates a prolog like the following:

 3ff8001c3fa: eb67f0480024   stmg    %r6,%r7,72(%r15)
 3ff8001c400: ebcff0780024   stmg    %r12,%r15,120(%r15)
 3ff8001c406: b904001f       lgr     %r1,%r15      <- load backchain
 3ff8001c40a: 41d0f048       la      %r13,72(%r15) <- load adjusted bfp
 3ff8001c40e: a7fbfd98       aghi    %r15,-616
 3ff8001c412: e310f0980024   stg     %r1,152(%r15) <- save backchain
