MDEV-21539 Assertion ...prtype... failed in row_log_table_apply_convert_mrec

Browse Source 
This bug is a cousin of MDEV-18719 and MDEV-20190, which failed to
relax a debug assertion in one more code path.

row_log_table_apply_convert_mrec(): Use dict_col_t::same_format()
and ignore all format-agnostic flags in the assertions.
