There seems to be a problem with replacing blackhole fdb entries as
fdb_find_rcu() does not find the associated fdb entry (addr, vid) and
I don't know why that is the case?

I realize that the reason why fdb_find_rcu() does not find the entry is surely that it is stored in the bridge device fdb and not 'master' fdb.
