lib/debugfs: Check if debufs is already mounted before attempting to mount it
mount("/sys/kernel/debug") will return an error if something is already
mounted there. So let's check for that before calling mount(). This
allows many of the tools (eg. intel_reg) to work even when no drm
drivers are loaded since the earlier "/sys/kernel/debug/dri" & co.
path checks will fail in that case and we will fall back to attempting
to mount debugfs ourselves.
