[PATCH] USB: gadget: prevent unnecessary warning message

[PATCH] USB: gadget: prevent unnecessary warning message

[Sascha Hauer]

The USB gadget autostart code issues a warning when no otg device
exists:

Cannot set parameter otg.mode: No such device

This is unnecessary since there may be no otg device at all, but only a
gadget device. Drop that warning by checking if there is a otg device
first.
