Bluetooth: btusb: avoid unused function warning 

The btusb_rtl_cmd_timeout() function is used inside of an
ifdef, leading to a warning when this part is hidden
from the compiler:

drivers/bluetooth/btusb.c:530:13: error: unused function 'btusb_rtl_cmd_timeout' [-Werror,-Wunused-function]

Use an IS_ENABLED() check instead so the compiler can see
the code and then discard it silently.
