    Use kvm own refcounting instead of playing with ->filp->f_count.
    That will allow to get rid of a lot of crap in anon_inode_getfd() and
    kill a race in kvm_dev_ioctl_create_vm() (file might have been closed
    immediately by another thread, so ->filp might point to already freed
    struct file when we get around to setting it).
