ubifs: setflags: Don't show error message when vfs_ioc_setflags_prepare() fails
Following process will trigger ubifs_err: 1. useradd -m freg (Under root) 2. cd /home/freg && mkdir mp (Under freg) 3. mount -t ubifs /dev/ubi0_0 /home/freg/mp (Under root) 4. cd /home/freg && echo 123 > mp/a (Under root) 5. cd mp && chown freg a && chgrp freg a && chmod 777 a (Under root) 6. chattr +i a (Under freg) UBIFS error (ubi0:0 pid 1723): ubifs_ioctl [ubifs]: can't modify inode 65 attributes chattr: Operation not permitted while setting flags on a This is not an UBIFS problem, it was caused by task priviliage checking on file operations. Remove error message printing from kernel just like other filesystems (eg. ext4), since we already have enough information from userspace tools.
