CAUTION:
Disabling EEH operation on a slot is highly discouraged, because it
can cause system crash or worse, data corruption.
This service can only be called by the single-function adapter drivers. If the service fails for a hardware or firmware reason, an error is logged.
Multifunction drivers call this service indirectly via eeh_clear(). It fails with EEH_FAIL if called directly by a multifunction driver.
The macro EEH_DISABLE_SLOT(handle) is provided for device drivers to call this service.
