bpf, x86: Simplify the parsing logic of structure parameters

Browse source

[ Upstream commit 7f78804957 ]

Extra_nregs of structure parameters and nr_args can be
added directly at the beginning, and using a flip flag
to identifiy structure parameters. Meantime, renaming
some variables to make them more sense.
