It turns out that devfs_close() does a dev_refthread() before invoking
device specific d_close(), which makes subsequent destroy_dev() being
blocked in the "devdrn" loop.

This bandaid should fix the smbfs hang/crashing observed on -CURRENT since
the introduction of sys/kern/kern_conf.c:1.199:

 	# mount_smbfs -I server //server/share /mnt
 	Password:
 	[hang]
