libpayload: usb: dwc2: check device connect state before enable channel
If the device has already been disconnected then we shouldn't enable
host channel to start any transfer, otherwise this channel goes into
an odd state the channel is enabled but can not be disabled by set
hcchar.chdis=1. So we need check the device connect status before
enable channel.
