[ Upstream commit 42d22098127d6384f789107f59caae87d7520fc4 ]
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.
Fixes: d7ef0d1e3968 ("Bluetooth: btusb: Use cmd_timeout to reset Realtek device")
