Daniel Borkmann d806a0cf2a bpf, x64: save several bytes when mul dest is r0/r3 anyway
Instead of unconditionally performing push/pop on rax/rdx
in case of multiplication, we can save a few bytes in case
of dest register being either BPF r0 (rax) or r3 (rdx)
since the result is written in there anyway.
