Herbert Xu 6c9e2c11c3 ipv6: raw: Deduct extension header length in rawv6_push_pending_frames
commit cb3e9864cdbe35ff6378966660edbcbac955fe17 upstream.

The total cork length created by ip6_append_data includes extension
headers, so we must exclude them when comparing them against the
IPV6_CHECKSUM offset which does not include extension headers.
