net/tls: Fix another skb memory leak when running kTLS traffic

This patch is a followup to
commit ffef737fd037 ("net/tls: Fix skb memory leak when running kTLS traffic")

Which was missing another sk_defer_free_flush() call in
tls_sw_splice_read().

Fixes: f35f821935d8 ("tcp: defer skb freeing after socket lock is released")
