Linus Torvalds f5b7769eb0 Revert "debugfs: inode: debugfs_create_dir uses mode permission from parent" ...

This reverts commit 95cde3c59966f6371b6bcd9e4e2da2ba64ee9775.

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/.  See
kvm_create_vm_debugfs()
