Resolves: fdo#60144 only delete *unposted* SfxRequests accumulated during lock

When the dispatched is locked, SfxRequests accumulate in aReqArr for later
dispatch when unlocked via Post

The pointers are typically deleted in Post, so only if we never get around to
posting them do we delete the unposted requests.
