can: peak_usb: force the string buffer NULL-terminated
strncpy() does not ensure NULL-termination when the input string size equals to the destination buffer size IFNAMSIZ. The output string is passed to dev_info() which relies on the NULL-termination. Use strlcpy() instead. This issue is identified by a Coccinelle script.
