packet: do not set TP_STATUS_CSUM_VALID on CHECKSUM_COMPLETE

stable inclusion
from stable-v4.19.268
commit 36e4b80042d2cd724335e75df492682cc9096dec
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I69KBO


CVE: NA

--------------------------------

[ Upstream commit b85f628a ]

CHECKSUM_COMPLETE signals that skb->csum stores the sum over the
entire packet. It does not imply that an embedded l4 checksum
field has been validated.

Fixes: 682f048b ("af_packet: pass checksum validation status to the user")
