SCSI: bfa: Chinook quad port 16G FC HBA claim issue

Browse source 
commit dcaf9aed99 upstream.

Bfa driver crash is observed while pushing the firmware on to chinook
quad port card due to uninitialized bfi_image_ct2 access which gets
initialized only for CT2 ASIC based cards after request_firmware().
For quard port chinook (CT2 ASIC based), bfi_image_ct2 is not getting
initialized as there is no check for chinook PCI device ID before
request_firmware and instead bfi_image_cb is initialized as it is the
default case for card type check.

This patch includes changes to read the right firmware for quad port chinook.
