nimble/ll: Fix data fragmentation with maxTxTime<maxTxOctets

Browse Source 
We did not properly adjust payload length for 2nd and subsequent packet
fragments so in case effectiveMaxTxTime is less than time required to
send payload of effectiveMaxTxOctets, we send too many data in all
packets except 1st one.
