net: fix __dev_kfree_skb_any() vs drop monitor

net: fix __dev_kfree_skb_any() vs drop monitor

BugLink: https://bugs.launchpad.net/bugs/2011430
[ Upstream commit ac3ad19584b26fae9ac86e4faebe790becc74491 ]

dev_kfree_skb() is aliased to consume_skb().

When a driver is dropping a packet by calling dev_kfree_skb_any()
we should propagate the drop reason instead of pretending
the packet was consumed.

Note: Now we have enum skb_drop_reason we could remove
enum skb_free_reason (for linux-6.4)

v2: added an unlikely(), suggested by Yunsheng Lin.
