usb: gadget: f_cdev: Fix memory leak with func_name



func_name related memory is allocated on creating instance of driver with
cser_set_inst_name() API with usage of kstrndup(). If cser_set_inst_name()
returns non-zero value or driver instance is released, this func_name
related memory is not freed. Fix this memory leak by freeing func_name from
cser_free_inst() API.
