For incoming SCO connection with transparent coding format, alt setting
of CVSD is getting applied instead of Transparent.

usb: dwc2: Fix HCD port connection race
1cf1bd8 
On Raspberry Pis without onboard USB hub frequent device reconnects
can trigger a interrupt storm after DWC2 entered host clock gating.
This is caused by a race between _dwc2_hcd_suspend() and the port
interrupt, which sets port_connect_status. The issue occurs if
port_connect_status is still 1, but there is no connection anymore:

usb 1-1: USB disconnect, device number 25

So avoid this by reading the connection status directly.
