linuxkpi: include missing linux/device.h

At the moment, struct device is accidentally defined by FreeBSD. This
was noticed when upgrading TC/BSD from 13.0 to 13.1 because FreeBSD
changed the name of it's struct device to struct _device.

Add the linux device header to include the Linux definition of struct
device.
