Michael Chan 72bb72b0d9 tg3: Prevent system hang during repeated EEH errors. 
The current tg3 code assumes the pci_error_handlers to be always called
in sequence.  In particular, during ->error_detected(), NAPI is disabled
and the device is shutdown.  The device is later reset and NAPI
re-enabled in ->slot_reset() and ->resume().

In EEH, if more than 6 errors are detected in a hour, only
->error_detected() will be called.  This will leave the driver in an
inconsistent state as NAPI is disabled but netif_running state is still
true.  When the device is later closed, we'll try to disable NAPI again
and it will loop forever.

We fix this by closing the device if we encounter any error conditions
during the normal sequence of the pci_error_handlers.

v2: Remove the changes in tg3_io_resume() based on Benjamin Poirier's
    feedback.
