i460_mux: correctly reset subchannels

When a subchannel is deleted or created the initalization mainly
consists of a memset over the wohle subchannel struct a message buffer
initailization.

However, when we delete a subchannel we also must take of the resetting
of the related struct. Currently this is done with a memest.
Unfortunately this creates not only a memory leak (there might be still
items in the multiplexer tx queue) but also it makes the application
crash when the message buffer is used the next time since the llist_head
of the tx queue looses its initialization.

Lets fix the memory leak problem and the message buffer problem and put
the reset functionality in a single place.
