can: peak_usb: force the string buffer NULL-terminated

[ Upstream commit e787f19373b8a5fa24087800ed78314fd17b984a ]

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.
