Return the device_t associated with the path.

When a SIM is created, it registers a bus with a NEWBUS device_t. This is stored in the internal cam_eb bus structure. There is no guarnatee any given path will have a device_t associated with it (it's legal to call xpt_bus_register with a NULL device_t.

Parameters

path	Path to return the device_t for.
