 Change from CAM_TID_INVALID to CAM_SEL_TIMEOUT error code when the usb device
 has been yanked, this works around a cam recounting bug when
 CAM_DEV_UNCONFIGURED is set late in the detach. In certain conditions the
 reference to the XPT device would not be released which would cause the usb
 explore thread to sleep forever on "simfree", preventing any new usb devices to
 be found/ejected on the bus.
