scsi: Constify struct pci_error_handlers

'struct pci_error_handlers' are not modified in these drivers.

Constifying these structures moves some data to a read-only section, so
increase overall security, especially when the structure holds some
function pointers.

On a x86_64, with allmodconfig, as an example:
Before:
======
   text	   data	    bss	    dec	    hex	filename
  39049	   6429	    112	  45590	   b216	drivers/scsi/aacraid/linit.o

After:
=====
   text	   data	    bss	    dec	    hex	filename
  39113	   6365	    112	  45590	   b216	drivers/scsi/aacraid/linit.o
