wireguard: queueing: use CFI-safe ptr_ring cleanup function
commit ec59f128a9bd4255798abb1e06ac3b442f46ef68 upstream.
We make too nuanced use of ptr_ring to entirely move to the skb_array
wrappers, but we at least should avoid the naughty function pointer cast
when cleaning up skbs. Otherwise RAP/CFI will honk at us. This patch
uses the __skb_array_destroy_skb wrapper for the cleanup, rather than
directly providing kfree_skb, which is what other drivers in the same
situation do too.
