libmsc: Fix wrong handling of user_message_reference parameter
libsmpp34 already converts received TLV integer values to native
endianess in libsmpp34_(un)pack.
Converting them again at receive time swaps the 2 bytes of
user_message_reference, then using a wrong value. As GSM03.40 spec
uses only 1 byte for the id, then only the high byte of the initial
value is used and eventually sent back to the ESME. Again, at that time,
htons() is not needed because libsmpp34 already handles that part.
See OS-#2429 for more details.
