While touching seccomp code I realized that the struct seccomp_data
argument to secure_computing() seems to be unused by all current
callers. So let's remove it unless there is some subtlety I missed.
Note, I only tested this on x86.

What was amluto thinking in

2f275de5d1ed ("seccomp: Add a seccomp_data parameter secure_computing()")

IIRC there was a period of time in which x86 used secure_computing()
for normal syscalls, and it was a good deal faster to have the arch
code supply seccomp_data.  x86 no longer works like this, and syscalls
aren't fast anymore ayway :(
