[PATCH] ip_output: account for fraggap when checking to add trailer_len

Browse Source 
During other work I noticed that ip_append_data() seemed to be forgetting to
include the frag gap in its calculation of a fragment that consumes the rest of
the payload.  Herbert confirmed that this was a bug that snuck in during a
previous rework.
