BUG/MINOR: cfgparse-listen: fix ebpt_next_dup pointer dereference on proxy "from" inheritance

ebpt_next_dup() was used 2 times in a row but only the first call was
checked against NULL, probably assuming that the 2 calls always yield the
same result here.

gcc is not OK with that, and it should be safer to store the result of
the first call in a temporary var to dereference it once checked against NULL.

This should fix GH #1869.
Thanks to Ilya for reporting this issue.

It may be backported up to 2.4.
