Eric Dumazet ce83060743 net: add pskb_may_pull_reason() helper

[ Upstream commit 1fb2d41501f38192d8a19da585cd441cf8845697 ]

pskb_may_pull() can fail for two different reasons.

Provide pskb_may_pull_reason() helper to distinguish
between these reasons.

It returns:

SKB_NOT_DROPPED_YET           : Success
SKB_DROP_REASON_PKT_TOO_SMALL : packet too small
SKB_DROP_REASON_NOMEM         : skb->head could not be resized
