DEVFS completely bypasses the cdevsw and bdevsw tables now.

Browse Source 
Each devfs node has (and has had fro a while) a pointer directly to
the correct cdefsw entry so just use it instead of doing the lookup.

There are several other places in the kernel that still use the tables
however, so they can't go away yet..
