pimd: Allow multiple secondary addresses to work

Suppose you have more than 2 addresses on a pim interface:
lo              up      default         10.255.0.1/32
                                        10.255.0.101/32
                                        10.255.0.254/32

A `show ip pim int lo` gives us this:

eva# show ip pim interface lo
Interface  : lo
State      : up
Address    : 10.255.0.1 (primary)
             10.255.0.101/32

When we go look at the code that pulls secondary addresses in
we are using a prefix_cmp to know if we know about a secondary already
but were expecting true values instead of -1/0/1 being returned.

Modify code so that pim sees all secondary addresses
