wifi: rtlwifi: set initial values for unexpected cases of USB endpoint priority

Browse source 
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.
