The function index_param() in servers/slapd/back_ldbm/index.c assigns *prefixp
with ber_bvstrdup() allocated data if it returns successfully. This function is
called from 3 places in servers/slapd/back_ldbm/filterindex.c (and from nowhere
else). The allocated data (pointed to by the variable 'prefix') is never freed.
This freeing should *always* be done (with ber_bvfree()) if index_param()
returns LDAP_SUCCESS, even if the calling functions itself doesn't return
successfully after the call of index_param().
