can: sja1000: 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
'name' is passed to dev_info which relies on NULL-termination.
Use strlcpy() instead.
This issue is identified by a Coccinelle script.
