These are just helpers so carry them over, this was added via commit
9e903e0852 through v3.2. The skb frag size was in place for a long time but
was changed from __u16 to __u32 via commit a309bb072b through v2.6.23 and
since we backport for >= 2.6.25 just leave this as is. This was already
only partly backported, this adds the missing helpers.

net: add skb frag size accessors
To ease skb->truesize sanitization, its better to be able to localize
all references to skb frags size.
Define accessors : skb_frag_size() to fetch frag size, and
skb_frag_size_{set|add|sub}() to manipulate it.
