[PATCH] USB: get rid of minor log spamming

Routine cases like handoff-to-companion shouldn't trigger diagnostics.
This gets rid of some recently added log spamming.  It's routine for
hub_port_wait_reset() to return -ENOTCONN to indicate handoff from
highspeed hubs to companions, so an error message is incorrect.
