Fix race conditions in ROOT_XFS_QuotaTest.NoCheckpointRecovery.
Fix race conditions in ROOT_XFS_QuotaTest.NoCheckpointRecovery.

There are two race conditions in
ROOT_XFS_QuotaTest.NoCheckpointRecovery. The first is when we were
checking the disk resources consumed without knowing whether the dd
command had completed. We can just eliminate this check since other
tests cover the resource usage case. The second race was installing the
MesosContainerizerProcess::___recover expectation after starting the
slave. We need to install this before starting.
