tracing: Have trace buffer point back to trace_array

commit dced341b2d4f06668efaab33f88de5d287c0f45b upstream.

The trace buffer has a descriptor pointer that goes back to the trace
array. But it was never assigned. Luckily, nothing uses it (yet), but
it will in the future.

Although nothing currently uses this, if any of the new features get
backported to older kernels, and because this is such a simple change,
I'm marking it for stable too.

Fixes: 12883efb670c "tracing: Consolidate max_tr into main trace_array structure"
