ea: query each superblock for named attr support

Browse source 
adds a new function nfs41_superblock_getattr(), which adds an OPENATTR call with createdir=0 after the GETATTR to check for named attribute support.  OPENATTR will either return ERR_NOTSUPP if not supported, or OK/ERR_NOENT depending on whether named attributes are present on the given file.  we can't query for the 'named_attr' attribute, because it only tells us whether the given file contains named attributes

if named attributes are supported on a superblock, it will return FILE_SUPPORTS_EXTENDED_ATTRIBUTES for associated volume queries
