kurogeek f121a3ec30 stellio: drop mt7530 get_stats64 kernel patch, in 6.18.58
Upstream 07d9958739 was backported to linux-6.18.y as af98611ad109
(2026-10-15) and is in the 6.18.58 nixpkgs now builds for stellio.
Applying the patch on top fails: patch(1) rejects all 10 hunks as
already applied, so the kernel build has been broken since the nixpkgs
bump brought 6.18.58.

# (the router needs logs for pppd/kea debugging and, after the Sep 2026
# unlogged reboots, for post-mortem; volatile storage left nothing).
# /tmp is tmpfs, no core dumps, and ext4 skips atime updates and
# flushes its journal every 60 s instead of 5 s so the small periodic
# writes (Kea leases, timesyncd clock, speedtest textfile, journal)
# coalesce. A power cut loses at most a minute of that state.
