ns: Force a defined state when sending NS RESETzecke/release/0.7-dev
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.
