devices: Use path to check device type
FreeBSD device numbers cannot be used to check the type of a device, as
they are merely unique filesystem IDs.
As the paths we use have been sanitized with realpath, we can simply use
the path to check if a requested file is an evdev or drm device. This
also allows us to make the check before the file is opened.
