Change subject: hnbgw: drop dead code from MSC_UnitdataCallback

PS1:
OK, I remember now.

a) not used:
osmo-hnbgw has only recently started sending RANAP UnitData by its own 
initiative.
Until very recently, osmo-hnbgw has only responded to receiving a RESET, with 
an ACK.
It has never sent a RESET message to the peer, here titan.
Also on RANAP, the HNBGW_Tests.ttcn so far conveniently ignored RANAP RESET 
handling.
In short, this UnitDataCallback so far never happened.

b) makes no sense:
The UnitDataCallback happens when osmo-hnbgw sends a RANAP UnitData to titan:
so currently, in response to receiving any UnitData message, the code responds 
with a RESET. That is not logical at all.

(What would make sense: when receiving a RESET, respond with RESET ACK. But:
Proper handling of RANAP RESET in ttcn actually happens in RAN_Emulation.ttcnpp)
