ext4: trim return value and 'dir' argument from ext4_insert_dentry()
In the initial implementation of ext4 encryption, the filename was encrypted in ext4_insert_dentry(), which could fail and also required access to the 'dir' inode. Since then ext4 filename encryption has been changed to encrypt the filename earlier, so we can revert the additions to ext4_insert_dentry().
