f2fs: fix to set inode->i_mode correctly for posix_acl_update_mode

Browse source

We should update the ~S_IRWXUGO part of inode->i_mode in __setattr_copy,
because posix_acl_update_mode updates mode based on inode->i_mode,
which finally overwrites the ~S_IRWXUGO part of i_acl_mode with old i_mode.

Testcase to reproduce this bug:
0. adduser abc
1. mkfs.f2fs /dev/sdd
2. mount -t f2fs /dev/sdd /mnt/f2fs
3. mkdir /mnt/f2fs/test
4. setfacl -m u🔤r /mnt/f2fs/test
5. chmod +s /mnt/f2fs/test
