This reverts commit b73d037.
This commit seems to have introduced a race condition where we can concurrently keep updating state after we've checked if we need to increase the serial, and thus end up writing partial changes to the state backend.
In the case of Terraform Enterprise, this fails altogether becauseof the state hash consistency check it does.
This fixes #15175.
