ANDROID: USB: f_accessory: Check dev pointer before decoding ctrl request

In case of poweroff charging mode, accessory function instance
is not created and due to this, _acc_dev will be NULL. If target
is connected to Accessory dock in poweroff charging mode, there
is a chance dev pointer is accessed, which is NULL. Hence add a
check before processing control request and return error if it is
NULL.
