There are scenario when the BindingStop service of PartitionDxe driver be re-entered. An example will be ejecting a DVD from a SATA DVDROM and then run "reconnect -r" under shell. In this specific case, part of the calling stack will be: PartitionDriverBindingStop() (PartitionDxe) -> Stop first child handle (PartitionDxe) -> ScsiDiskFlushBlocksEx() (ScsiDiskDxe) -> A media change is detected (ScsiDiskDxe) -> Reinstall of BlockIO(2) protocols (ScsiDiskDxe) -> Entering PartitionDriverBindingStop() again (PartitionDxe) -> Potential risk of referencing already stopped child handle (PartitionDxe) ... The current code has potential issue of referencing of already stopped child handle. This commit adds re-entry handling logic to resolve such issue.
