HADOOP-19089: [ABFS] Reverting Back Support of setXAttr() and getXAttr() on root path (#6592)

Browse Source 
This reverts most of
HADOOP-18869: [ABFS] Fix behavior of a File System APIs on root path (#6003).

Calling getXAttr("/") or setXAttr("/") on an abfs container will fail with

`Operation failed: "The request URI is invalid.", HTTP 400 Bad Request`

 
This change is to ensure:
* Consistency across ADLS clients
* Consistency across authentication mechanisms.
