[knet]: Disable NETIF_F_HW_CSUM in KNET (#17080)

Browse Source 
This is CSP CS00012280996.
The issue to fix is that the checksum was incorrect for all TCP packets leaving the system so that the BGP connection cannot be established. We found the issue on BCM56993, and it is possible to affect all platforms using linux_ngknet.
