perf/x86/64: Simplify regs_user->abi setting code in get_regs_user()
user_64bit_mode(regs) basically checks regs->cs to point to a
64-bit segment. This check used to be unreliable here because
regs->cs was not always correct in syscalls.
Now regs->cs is always correct: in syscalls, in interrupts, in
exceptions. No need to emply heuristics here.
