    ns: Force a defined state when sending NS RESET
    
    Currently the state is assumed to remain the same while the reset
    procedure is active. While this works correctly in general, a single
    unexpected BLOCK_ACK or UNBLOCK_ACK can change the state but will not
    stop the reset procedure. The leads to repeated RESET messages, where
    the corresponding RESET_ACK is ignored. This is a stable state which
    can only be left by manual intervention or by reception of a RESET
    message from the peer.
    
    This commit changes the RESET timeout handler to set the state to
    BLOCKED/RESET when sending the new NS RESET message.
    
    Note that this should ensure a clean restart even if the state has been
    screwed up. It does not fix the handling of BLOCK_ACK or UNBLOCK_ACK
    in abnormal cases.
    
    Addresses:
     gprs_ns.c:349 NSEI=8895 Tx NS RESET (NSVCI=8895, cause=O&M intervention)
     gprs_ns.c:878 NSVCI=8895 Rx NS RESET ACK (NSEI=8895, NSVCI=8895)
     gprs_ns.c:887 NS RESET ACK Discarding unexpected message for NS-VCI 8895 from SGSN NSEI=8895
