diag: Allow DCI packets to be copied separately 



Presently DCI packets are copied to userspace together with
few other packet types like mask update, hdlc updates failing
dci packet processing in diag library. Allow DCI packets
to be copied to userspace separately by changing the exit
condition for copying other packet types.
