hfsplus: Remove the duplicate attr inode dirty marking action
Description

In the Linux kernel, the following vulnerability has been resolved: hfsplus: Remove the duplicate attr inode dirty marking action Syzbot reported a null-ptr-deref in [1]. If the attributes file is not loaded during system mount, a trigger occurs [1] when setxattr is executed in userspace. Remove the first mark attr inode dirty operation.
