82c17bc9fa rpcclient: Fix "capabilities" command
This used to not properly store the chained credentials back into the
netlogon_creds_cli tdb. This by the way is the bug that all the
routines for the NT4 style sam replication had that just disappeared.

and the default stream of a file or directory is accessed. In that case
streams_xattr_open does not allocate the stream_io fsp extension. The
DBG_DEBUG message in streams_xattr_fstat tries to access the stream_io
before checking for a NULL value, resulting in the crash. Fix this by
