s3: client : Add extra return parameter to all client open calls.

s3: client : Add extra return parameter to all client open calls.

Add a return parameter of struct smb_create_returns *cr to
cli_ntcreate()
cli_ntcreate_recv()
cli_nttrans_create()
cli_nttrans_create_recv()

Always pass in NULL for now. This fixes the create
API to always fully return the data the server has
given back to us on the open file to the caller.
