makedevs: don't restrict device node paths to 40 characters 

40 character paths work OK for device nodes in /dev but not for
device nodes created in a chroot, LXC container, etc.

Since the 'path' array is already a 4k buffer, the sscanf 40
character limit seems to be a typo or historical mis-merge. Update
the sscanf limit and bring the code in sync with the Buildroot
version:
