chardev/mux: convert size members to unsigned int

Browse source 
There is no sense to keep `focus`, `mux_cnt`, `prod`, `cons`
and `tag` variables as signed, those represent either size,
either position in array, which both are unsigned.

`focus` member of `MuxChardev` is kept signed, because initially
set to -1.
