zebra: Continue fpm_read when we decide a netlink message is not needed

donaldsharp · donaldsharp · commit c0275ab189d6 · 2023-01-10T08:36:50.000-05:00
When FRR receives a netlink message that it decides to stop parsing
it returns a 0 ( instead of a -1 ).  Just make the dplane continue
reading other data instead of aborting the read.
