x1000: fix hang that may occur in USB mode

Browse source 
Upon getting a USB reset, the USB core will update charging
current by calling usb_charging_maxcurrent_change(). On all
current X1000 targets this may cause a hang, since changing
the charge current involves a blocking I2C transaction.

Eg. if the host issues a reset when we're already configured
as part of error recovery, the change from 500 mA -> 100 mA
will cause a hang.
