MDEV-11317: ! is_set()' or !is_set() || (m_status == DA_OK_BULK && is_bulk_op())' fails in Diagnostics_area::set_ok_status on CREATE OR REPLACE with ARCHIVE table

Problem was with deleting non existing .frm file for a storage engine that
doesn't have .frm files (yet)

Fixed by not giving an error for non existing .frm files for storage engines
that are using discovery
Fixed also valgrind supression related to the given test case
