[ros-diffs] [ion] 22767: - Move IoGetBaseFileSystemDeviceObject to device.c and make it check for FO_DIRECT_DEVICE_OPEN, which it wasn't before (and also code it in a less confusing way like the other IoGetXxxDeviceObject APIs) - Mask out the DO_VERIFY_VOLUME flag when mounting a device.

Log:
- Move IoGetBaseFileSystemDeviceObject to device.c and make it check for
FO_DIRECT_DEVICE_OPEN, which it wasn't before (and also code it in a less confusing
way like the other IoGetXxxDeviceObject APIs)
- Mask out the DO_VERIFY_VOLUME flag when mounting a device.
