sctp: fix erroneous inc of snmp SctpFragUsrMsgs

Browse Source 
Currently it is incrementing SctpFragUsrMsgs when the user message size
is of the exactly same size as the maximum fragment size, which is wrong.

The fix is to increment it only when user message is bigger than the
maximum fragment size.
