USB: serial: ftdi_sio: silence jtag probe
Probe of a device should generally be silent unless errors are
encountered.
Stop logging that the JTAG port is ignored when probing devices with
such a reserved port.
This also maintains consistency with devices that match on interface
number to avoid binding to reserved ports.
Note that the message is not even correct for the second port of the ST
Micro Connect Lite.
