Map USB endpoints to hardware and AC queues according to number of USB endpoints. However, original only give a warning for unexpected cases but initial values are not given. Then, smatch warns: drivers/net/wireless/realtek/rtlwifi/rtl8192cu/hw.c:642 _rtl92cu_init_chipn_two_out_ep_priority() error: uninitialized symbol 'valuelow'. drivers/net/wireless/realtek/rtlwifi/rtl8192cu/hw.c:644 _rtl92cu_init_chipn_two_out_ep_priority() error: uninitialized symbol 'valuehi'. drivers/net/wireless/realtek/rtlwifi/rtl8192cu/hw.c:649 _rtl92cu_init_chipn_two_out_ep_priority() error: uninitialized symbol 'valuehi'. drivers/net/wireless/realtek/rtlwifi/rtl8192cu/hw.c:650 _rtl92cu_init_chipn_two_out_ep_priority() error: uninitialized symbol 'valuelow'. The regular selection is high and low queues, so move default (unexpected) case along with that. Compile tested only.
