edid: Don't half parse (and wrongly print) more detailed timings

The EDID parsing code continued to update _some_ fields of the output
edid but not others if "did_detailed_timing" was already set.  It also
then went on to print out this halfway mix of modes each time, despite
the fact that it didn't really update everything.

Let's fix that.  We'll reduce code changes by using a temporary copy of
data in detailed_block() and then we'll copy it back if we decide we
should update.
