The partition is still marked as type "Apple_HFS" in the partition
table. MacOS always tries to mount partitions of that type. It sees
gibberish instead of a valid HFS or HFS+ volume, so it complains at
you.
Use pdisk under Linux to delete that partition, then recreate it.
Make sure you get the starting block and size EXACTLY the same as
they were before. pdisk will make the replacement partition table
entry have type "Apple_UNIX_SVR2", which will make MacOS ignore it.
(If you're paranoid, back up what's on that partition and others
before doing this. I've successfully done stuff like this with no
backup -- pdisk only alters the partition table, not partition
contents.)
