[PATCH wireless-next] wifi: cfg80211: use strscpy in cfg80211_wext_giwname

[Thorsten Blum]

strcpy() has been deprecated [1] because it performs no bounds checking
on the destination buffer, which can lead to buffer overflows.

While the current code works correctly, replace strcpy() with the safer
strscpy() to follow secure coding best practices.
