tls: rx: strp: set the skb->len of detached / CoW'ed skbs
[ Upstream commit 210620ae44a83f25220450bbfcc22e6fe986b25f ]
alloc_skb_with_frags() fills in page frag sizes but does not
set skb->len and skb->data_len. Set those correctly otherwise
device offload will most likely generate an empty skb and
hit the BUG() at the end of __skb_nsg().
