can: sja1000: force the string buffer NULL-terminated

[ Upstream commit cd28aa2e056cd1ea79fc5f24eed0ce868c6cab5c ]

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.
