PURGE CHANGED_PAGE_BITMAPS doesn't work when innodb_data_home_dir used

For PS 5.7 PURGE CHANGED_PAGE_BITMAPS doesn't work when innodb_data_home_dir is used to move innodb's data outside of mysqls' data directory.

Steps to reproduce:

1. Run MySQL with:

[mysqld]
innodb_track_changed_pages=1
innodb_max_bitmap_file_size = 4096
innodb_data_home_dir = /test01/innodb

2. Generate some inserts

3. Execute 

PURGE CHANGED_PAGE_BITMAPS BEFORE lsn;
