Subject: [PATCH] wilc1000: replace deprecated strcpy() with strscpy()

strcpy() is deprecated for NUL-terminated strings.  Replace the single
instance in wilc1000 netdev setup with strscpy(), which guarantees
NUL-termination and prevents overflow.

ndev->name is a fixed-size buffer (IFNAMSIZ, 16 bytes).
