This changes the linux_wlan.c and wilc_wlan.c to do this for the most part. There are a few exceptions where these functions are themselves called from another part of the driver that does not have an instance pointer at hand. Changing those would be a follow-up step. There are a few other globals that will have to get moved into struct wilc at a later point.
