Commit 1af2dface5d2 ("af_unix: Don't access successor in unix_del_edges()
during GC.") fixed use-after-free by avoid accessing edge->successor while
GC is in progress.
However, there could be a small race window where another process could
call unix_del_edges() while gc_in_progress is true and __skb_q... | ```diff

ADMAv2.0 is plagued by RX hangs which can't easily detected and happen upon
receival of a corrupted Ethernet frame.
Use ADMAv1 instead which is also still present and usable, and doesn't
suffer from that problem.

Split tx and rx fields in mtk_soc_data struct. This is a preliminary
patch to roll back to ADMAv1 for MT7986 and MT7981 SoC in order to fix a
hw hang if the device receives a corrupted packet when using ADMAv2.0.
