Jason Evans 6fd53da030 Fix prof_tdata_get()-related regressions.
Fix prof_tdata_get() to avoid dereferencing an invalid tdata pointer
(when it's PROF_TDATA_STATE_{REINCARNATED,PURGATORY}).

Fix prof_tdata_get() callers to check for invalid results besides NULL
(PROF_TDATA_STATE_{REINCARNATED,PURGATORY}).

These regressions were caused by
602c8e0971160e4b85b08b16cf8a2375aa24bc04 (Implement per thread heap
profiling.), which did not make it into any releases prior to these
fixes.
