To be able to build linux-firmware 20260622, it is necessary to delete ACENIC drivers from Kernel config. With ACENIC drivers in, firmware build fails like: ``` * Missing firmware: acenic/tg2.bin (acenic.ko.xz) * Missing firmware: acenic/tg1.bin (acenic.ko.xz) * ERROR: sys-kernel/coreos-firmware-20260622::coreos-overlay failed (prepare phase): * Missing firmware ``` Fixes flatcar/Flatcar#2205 Signed-off-by: Dongsu Park <dongsu@dpark.io>

Pull request overview
Removes the legacy ACENIC kernel module from the coreos-modules common kernel config to avoid linux-firmware build failures due to missing acenic/tg{1,2}.bin firmware blobs (per Flatcar issue #2205).
Changes:
- Disable ACENIC by removing
CONFIG_ACENIC=mfrom the kernel module config fragment used bycoreos-modules(kernel 6.12).
