[PATCH net 2/2] net: mctp: usb: don't fail mctp_usb_rx_queue on a deferred submission

[Jeremy Kerr <jk@codeconstruct.com.au>]

In the ndo_open path, a deferred queue open will report a failure, and
so the netdev will not be ndo_stop()ed, leaving us with the rx_retry
work potentially pending.

Don't report a deferred queue as an error, as we are still operational.
This means we use the ndo_stop() path for future cleanup, which handles
rx_retry_work cancellation.
