Fix the crash happens in PrintPredictionUnitStats()

Root cause:
The call path
rd_pick_intrabc_mode_sb -> txfm_search -> PrintPredictionUnitStats
set tile_data to NULL and passed it into PrintPredictionUnitStats.

However PrintPredictionUnitStats always assumes tile_data to be non
NULL, which incurs the segmentation fault.

Solution:
Add NULL check in PrintPredictionUnitStats.
Turn on the stats dumping related to inter_mode_rd_models.
