PXB Table flags mismatch on stats with tables filter against MariaDB database with partitioned tables

[Vasily Nemkov]

PXB 2.3.8 was tested against the MariaDB 10.1.2, resulting in several tests failing with the same symptoms:
    ib_part_include
    ib_part_tf_innodb

PXB crashes when invoked with --stats and --tables (or --tables-file) producing following output:
InnoDB: Error: table flags are 0x400 in the data dictionary
InnoDB: but the flags in file ./test/test#P#p2.ibd are 0x0!

This could be because you hit a bug or data is corrupted.
This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.

Thread pointer: 0x0
Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...

Probably only affects partitioned tables.

[Sergei Glushchenko (sergei.glushchenko)]

Triaging as 'low' because --stats is really isn't used often
