MFC rev. 1.24 of the sys/fs/devfs/devfs_rule.c,
    rev. 1.218 of the sys/vm/vm_mmap.c

Do not dereference cdev->si_cdevsw, use the dev_refthread() to properly
obtain the reference. In particular, this fixes the panic reported in
the PR. Remove the comments stating that this needs to be done.

PR:	kern/119422
