x86, mpx: fix compile errors when tracing off

From: Dave Hansen <dave.hansen@linux.intel.com>

We DEFINE_TRACEPOINTS in arch/x86/mm/mpx.c, which is of course
only compiled when MPX is compiled in.

trace_bounds_exception_mpx() is used in bounds.c which is
outside the core MPX code and not under the MPX config option.
This can potentially end up being an undefined symbol.

So, we create a stub version of the function for when MPX is
off.  But, I screwed up where I placed the stub and its #else.
This puts them back in the right place.
