Subject: pimd: initialize prefix value in Auto-RP

pimd: initialize prefix value in Auto-RP

clang-SA complains that it's only partially initialized (because it's
used with IPv4 only).  The code later calls some AF-generic code,
prompting clang-SA to complain that the non-IPv4 parts are used without
being set.  While this shouldn't happen, just initialize it fully.
