Abhishek Chauhan 35c3e27917 Revert "net: Re-use and set mono_delivery_time bit for userspace tstamp packets" 
This reverts commit 885c36e59f.

The patch currently broke the bpf selftest test_tc_dtime because
uapi field __sk_buff->tstamp_type depends on skb->mono_delivery_time which
does not necessarily mean mono with the original fix as the bit was re-used
for userspace timestamp as well to avoid tstamp reset in the forwarding
path. To solve this we need to keep mono_delivery_time as is and
introduce another bit called user_delivery_time and fall back to the
initial proposal of setting the user_delivery_time bit based on
sk_clockid set from userspace.

Fixes: 885c36e59f ("net: Re-use and set mono_delivery_time bit for userspace tstamp packets")
