* volume: return error instead of panicking when .dat open fails

When backend.OpenVolumeFile returns an error (e.g. disk below
-minFreeSpace), dataFile is nil.  Calling backend.NewDiskFile(nil)
immediately after caused a nil-pointer panic in f.Stat()/f.Name().

Move the existing error check to run right after OpenVolumeFile, before
NewDiskFile is called, so the error is returned cleanly.

Fixes seaweedfs/seaweedfs#11615

* volume: share .dat load error handling

Extract datFileLoadError helper so open and create paths share one check.

* volume: trim dat-open-fail test comments

* volume(rust): cover unopenable .dat load path
