sctp: avoid NULL dereference when chunk data buffer is missing
...
[ Upstream commit 441f0647f7673e0e64d4910ef61a5fb8f16bfb82 ]
chunk->skb pointer is dereferenced in the if-block where it's supposed
to be NULL only.
chunk->skb can only be NULL if chunk->head_skb is not. Check for frag_list
instead and do it just before replacing chunk->skb. We're sure that
otherwise chunk->skb is non-NULL because of outer if() condition.
