Description

IndexBuildsCoordinatorMongod::_waitForNextIndexBuildAction() holds RSTL only for the while loop scope to perform primary check. Because of that, the primary check is no longer valid after this point. This can lead stepped down node(secondary) trying to commit or abort without getting commit/abortIndex oplog entry for 2 phase index builds. In turn, it results in this invariant failure.
