Devices are hardwired with "unit 0", not "lun 0" as was in these man pages.

Also, update the pass(4) man page to indicate that some CCBs must be
sent through the xpt(4) device and cannot be sent through a pass device.

+This ioctl takes most kinds of CAM CCBs and passes them through to the CAM
+transport layer for action.  Note that some CCB types are not allowed
+through the passthrough device, and must be sent through the

+XPT_DEV_MATCH, XPT_RESET_BUS, XPT_SCAN_LUN, XPT_ENG_INQ, and XPT_ENG_EXEC.
+These CCB types have various attributes that make it illogical or
+impossible to service them through the passthrough interface.
