Revert "debugfs: inode: debugfs_create_dir uses mode permission from parent"
This reverts commit 95cde3c5 . The commit had good intentions, but it breaks kvm-tool and qemu-kvm. With it in place, "lkvm run" just fails with Error: KVM_CREATE_VM ioctl Warning: Failed init: kvm__init which isn't a wonderful error message, but bisection pinpointed the problematic commit. The problem is almost certainly due to the special kvm debugfs entries created dynamically by kvm under /sys/kernel/debug/kvm/.
