mesh: Transport tx seg_o overflow

Browse Source 
Increases the transport segmentented tx seg_o counter to 6 bits to avoid
overflow when sending 32 segments. The check in the send loop would
previously never be false, which causes segments to repeat
unnecessarily.

this is port of e1c6ea9241e21942965eb66a62f13624c5528905
