Zero out unused totemsrp my_proc_list entries

When making my_proc_list smaller, ensure that the
now non-used entries are zero-ed out. There are some suspect
assert's that assume that there is always 2 entries in the list.
These fail when my_proc_list is reduced to 1 entry (and the
valid [0] entry is the same as the 'unused' [1] entry).
