For legacy chips without CLM blob files, kernel with user helper function
returns -EAGAIN when we request_firmware() for blob file. In this case,
brcmf_bus_started gets error and failed to bring up legacy chips.
Because of that, we should continue with CLM data currently present in
firmware if getting -EAGAIN when doing request_firmware().
