Subject: mei: bus: fix possible boundaries violation

From: Alexander Usyskin <alexander.usyskin@xxxxxxxxx>

commit cfda2794b5afe7ce64ee9605c64bef0e56a48125 upstream.

function 'strncpy' will fill whole buffer 'id.name' of fixed size (32)
with string value and will not leave place for NULL-terminator.
Possible buffer boundaries violation in following string operations.
Replace strncpy with strlcpy.
