Remove calls to pci_disable_device except in fail_all_cmds.  The
pci_disable_device function does something nasty to Smart Array controllers
that pci_enable_device does not undo.  So if the driver is unloaded it
cannot be reloaded.

Also, customers can disable any pci device via the ROM Based Setup Utility
(RBSU).  If the customer has disabled the controller we should not try to
blindly enable the card from the driver.  Please consider this for
inclusion.
