tracing, x86: function return tracer, fix assembly constraints

fix:

 arch/x86/kernel/ftrace.c: Assembler messages:
 arch/x86/kernel/ftrace.c:140: Error: missing ')'
 arch/x86/kernel/ftrace.c:140: Error: junk `(%ebp))' after expression
 arch/x86/kernel/ftrace.c:141: Error: missing ')'
 arch/x86/kernel/ftrace.c:141: Error: junk `(%ebp))' after expression

the [parent_replaced] is used in an =rm fashion, so that constraint
is correct in isolation - but [parent_old] aliases register %0 and uses
it in an addressing mode that is only valid with registers - so change
the constraint from =rm to =r.

This fixes the build failure.
