CVE-2025-40282

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: 6lowpan: reset link-local header on ipv6 recv path

Bluetooth 6lowpan.c netdev has header_ops, so it must set link-local
header for RX skb, otherwise things crash, eg. with AF_PACKET SOCK_RAW

Add missing skb_reset_mac_header() for uncompressed ipv6 RX path.

For the compressed one, it is done in lowpan_header_decompress().
