    ksmbd: count all requests in req_running counter
    
    [ Upstream commit 83c47d9e0ce79b5d7c0b21b9f35402dbde0fa15c ]
    
    This changes the semantics of req_running to count all in-flight
    requests on a given connection, rather than the number of elements
    in the conn->request list. The latter is used only in smb2_cancel,
    and the counter is not used
