Subject: [PATCH 1/6] scsi: mpt3sas: constify pci_error_handlers structures

These pci_error_handlers structures are only stored in the err_handler
field of a pci_driver structure, and this field is declared as const.  Thus
the pci_error_handlers structures can be const too.

Done with the help of Coccinelle.
