Subject: [PATCH v2] x86/entry64: remove unused audit related macros

These macro ocured in the 86a1c34a929f commit (x86_64 syscall audit
fast-path by Roland McGrath <roland@...hat.com>).

These defines were used in two-phase sycalls entry tracing, but
this functionality was moved to the syscall_trace_enter() from
arch/x86/entry/common.c in the 1f484aa69 commit (x86/entry: Move
C entry and exit code to arch/x86/entry/common.c by Andy Lutomirski
<luto@...nel.org>).

The syscall_trace_enter() now uses same defines from <linux/audit.h>,
so these defines are no longer used anywhere in entry_64.S and we may
remove them.
