Re: [PATCH v2] net: tun: replace strcpy with strscpy for ifr_name

Replace the strcpy() calls that copy the device name into ifr->ifr_name
with strscpy() to avoid potential overflows and guarantee NULL termination.

Destination is ifr->ifr_name (size IFNAMSIZ).

Tested in QEMU (BusyBox rootfs):
 - Created TUN devices via TUNSETIFF helper
 - Set addresses and brought links up
 - Verified long interface names are safely truncated (IFNAMSIZ-1)

v2:
- Dropped third argument from strscpy(), inferred from field size.
