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()
