scripts/decode_stacktrace.sh: code: preserve alignment
With lines having a code to decode, the alignment was not preserved for
the first line.
With this sample ...
[ 52.238089][ T55] RIP: 0010:__ip_queue_xmit+0x127c/0x1820
[ 52.238401][ T55] Code: c1 83 e0 07 48 c1 e9 03 83 c0 03 (...)
... the script was producing the following output:
[ 52.238089][ T55] RIP: 0010:__ip_queue_xmit (...)
[ 52.238401][ T55] Code: c1 83 e0 07 48 c1 e9 03 83 c0 03 (...)
That's because scripts/decodecode doesn't preserve the alignment. No need
to modify it, it is enough to give only the "Code: (...)" part to this
script, and print the prefix without modifications.
With the same sample, we now have:
[ 52.238089][ T55] RIP: 0010:__ip_queue_xmit (...)
[ 52.238401][ T55] Code: c1 83 e0 07 48 c1 e9 03 83 c0 03 (...)
