wifi: rtw88: Handle C2H_ADAPTIVITY in rtw_fw_c2h_cmd_handle()

Browse source

The firmware message C2H_ADAPTIVITY is currently handled in
rtw_fw_c2h_cmd_rx_irqsafe(), which runs in the RX workqueue, but it's
not "irqsafe" with USB because it sleeps (reads hardware registers).
This becomes a problem after the next patch, which will create the RX
workqueue with the flag WQ_BH.

To avoid sleeping when it's not allowed, handle C2H_ADAPTIVITY in
rtw_fw_c2h_cmd_handle(), which runs in the c2h workqueue.
