Fix a case in tcp_do_segment() where tcp_update_sack_list() would

be called with an incorrect segment end value.  tcp_reass() may
trim segments when they overlap with already existing ones in the
reassembly queue.  Instead of saving the segment end value before
the call to tcp_reass() compute it on the fly based on the effective
segment length afterwards.

This bug was not really problematic as no information got lost and
the eventual SACK information computation was correct nontheless.
