coresight-tmc: Ignore USB write errors during disconnection

Browse Source 
When USB sink path is disabled or disconnected, it is expected that
the outstanding write requests will return with an error code.
Ignore -ECONNRESET and -ESHUTDOWN for those respective cases to
avoid printing an error message to the kernel log.
