Title: Prevent NPE on getPathSize for non-existant file

Some FileSystem implementations (i.e. DistributedFileSystem) return
null (instead of throwing a FileNotFoundException) when listStatus
is called with a non-existant path. The null situation is now handled
instead of allowing an NPE to be thrown, and a warning is logged.
