scsi: message: fusion: Constify struct pci_device_id
'struct pci_device_id' is not modified in these drivers.
Constifying this structure moves some data to a read-only section, so
increase overall security.
On a x86_64, with allmodconfig, as an example:
Before:
======
text data bss dec hex filename
36999 2451 88 39538 9a72 drivers/message/fusion/mptfc.o
After:
=====
text data bss dec hex filename
37415 2043 88 39546 9a7a drivers/message/fusion/mptfc.o
