MDEV-21832 FORCE all partition to rebuild if any one of the

		partition does rebuild

- In ha_innobase::commit_inplace_alter_table() assumes that all partition
should do the same kind of alter operations. During DDL, if one partition
requires table rebuild and other partition doesn't need rebuild
then all partition should be forced to rebuild.
