MDEV-17909 Problem by MariaDB Update 10.1.32 -> 10.2.19 (Incorrect information in file: .frm)

Browse Source 
use frm_version, not mysql_version when parsing frm

In particular, virtual columns are stored according to
frm_version. And CHECK TABLE will overwrite mysql_version
to the current server version, so it cannot correctly
describe frm format.
