[PATCH v3] x86/entry64: remove unused audit related macros

[Alexander Kuleshov]

These macros were added in:

  86a1c34 ("x86_64 syscall audit fast-path")

commit. They were used in two-phase sycalls entry tracing,
but this functionality was moved to the
arch/x86/entry/common.c:syscall_trace_enter() in:

  1f484aa ("x86/entry: Move C entry and exit code to arch/x86/entry/common.c")

commit.

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

x86/entry64: Remove unused audit related macros

These macros were added in the following commit:

  86a1c34a929f ("x86_64 syscall audit fast-path")

They were used in two-phase sycalls entry tracing, but this functionality
was then moved to the arch/x86/entry/common.c:syscall_trace_enter() function,
in the following commit:

  1f484aa69046 ("x86/entry: Move C entry and exit code to arch/x86/entry/common.c")

syscall_trace_enter() now uses the defines from <linux/audit.h>,
so these defines entry_64.S are no longer used anywhere.
