[PATCH] wifi: rsi: Fix types to appease CFI

Avoids errors like:

    CFI failure at kthread+0x124/0x1cc (target: rsi_coex_scheduler_thread+0x0/0x1b4 [redpine_91x]; expected type: 0x89fb613d)

As seen in the aforementioned error this was tested using the downstream
redpine_91x driver found in the Librem 5's downstream source tree.
However, it appears that this driver is a modified version of the rsi
driver found in mainline Linux and as such I decided to port the changes
here too.
