[SCSI] aacraid: Restart adapter on firmware assert (Update 2)

Browse Source 
Received from Mark Salyzyn

If the adapter should be in a blinkled (Firmware Assert) state when the
driver loads, we will perform a warm restart of the Adapter Firmware to
see if we can rescue the adapter. Possible causes of a blinkled can
occur on some early release motherboard BIOSes, transitory PCI bus
problems on embedded systems or non-x86 based architectures, transitory
startup failures of early release drives or transitory hardware
failures; some of which can bite the adapter later at runtime. Future
enhancements will include recovery during runtime.

Fixed extra whitespace space issue.
