config: correctly break string for prefix filter
This if statement does the following:
1. Copy the value of "config prefix_filter"
2. Break the string at "/"
3. Save the number after / as prefix length
4. Convert the address before / into in6_addr
However the extraneous "=" broke the second step and inet_pton
failed with addresses with mask. This commit removes the = thus
fixes the feature.
