test/librbd: add test condition for whole-object switch with fast diff enable

This patch adds a test condition to test fast diff between two snapshots
with whole-object switch.

`TestMockObjectMapDiffRequest.EndDelta` expects diff state
`DIFF_STATE_DATA_UPDATED` which is an incorrect expectation when diff is calculated
between two snapshots.
