Hailong liu c11f7749f1 mm/page_alloc: add a missing mm_page_alloc_zone_locked() tracepoint ...

commit ce8f86ee94fabcc98537ddccd7e82cfd360a4dc5 upstream.

The trace point *trace_mm_page_alloc_zone_locked()* in __rmqueue() does
not currently cover all branches.  Add the missing tracepoint and check
the page before do that.
