nilfs2: use inode_set_flags() in nilfs_set_inode_flags()
Use inode_set_flags() to atomically set i_flags instead of clearing out
the S_IMMUTABLE, S_APPEND, etc. flags and then setting them from the
FS_IMMUTABLE_FL, FS_APPEND_FL flags to avoid a race where an immutable
file has the immutable flag cleared for a brief window of time.
This is a similar fix to commit 5f16f3225b06 ("ext4: atomically set
inode->i_flags in ext4_set_inode_flags()").
