cxgb4: FW upgrade fixes
[ Upstream commit 26747211486c5bc7dd014c3caab206576e00c0d0 ] Disable FW_OK flag while flashing Firmware. This will help to fix any potential mailbox timeouts during Firmware flash. Grab new devlog parameters after Firmware restart. When we FLASH new Firmware onto an adapter, the new Firmware may have the Firmware Device Log located at a different memory address or have a different size for it.
