CVE-2024-57948: In the Linux kernel, the following vulnerability has been resolved:  mac802154: check local interfaces before deleting sdata list  syzkaller reported a corrupted list in ieee802154_if_remove. [1]  Remove an IEEE 802.15.4 network interface after unregister an IEEE 802.15.4 hardware device from the system.

To avoid this issue, add a check for local->interfaces before deleting sdata list.  [1] kernel BUG at lib/list_debug.c:58!
