x86_64: fix ia32 AMD syscall audit fast-path
The new code in commit 5cbf1565f29eb57a86a305b08836613508e294d7 has a bug in the version supporting the AMD 'syscall' instruction. It clobbers the user's %ecx register value (with the %ebp value). This change fixes it. Signed-off-by: Roland McGrath <roland@redhat.com>
