usb: gadget: udc: renesas_usb3: Fix sysfs interface of "role"
Since the role_store() uses strncmp(), it's possible to refer
out-of-memory if the sysfs data size is smaller than strlen("host").
This patch fixes it by using sysfs_streq() instead of strncmp().
Fixes: cc995c9ec118 ("usb: gadget: udc: renesas_usb3: add support for usb role swap")
