usb: misc: ks_bridge: Fix probe failure on reconnect



Currently the driver does not mark ksb->ifc to NULL explicitly
as a part of bridge_disconnect. When the probe is tried for the
next time, it finds ksb->ifc to be in use and bails out. To fix
this, mark ksb->ifc to NULL as a part of _disconnect.
