KZone zvol chown ownership issue

Set the owner to any non-root user and access a device with “ls -lL” as non-root, it immediately changes the owner to root:sys.
This happens for Sybase zones that got patched.

Example :

After a Solaris upgrade to 11.4 SRU 71.170.2 Sybase will not start. The database uses RAW filesystems that need to be owned by "SYBASE" user account. After the SRU update, if user sybase tried to read or
write or just do an "ls -lL" of the raw filesystem directory all files would change permission from sybase to root.

Downgrade to 11.4.59.144.2 resolved the problem. Permissions stayed consistent. This is on a kernel zone.
