Menglong Dong f8319dfd1b net: tcp: reset 'drop_reason' to NOT_SPCIFIED in tcp_v{4,6}_rcv() 
The 'drop_reason' that passed to kfree_skb_reason() in tcp_v4_rcv()
and tcp_v6_rcv() can be SKB_NOT_DROPPED_YET(0), as it is used as the
return value of tcp_inbound_md5_hash().

And it can panic the kernel with NULL pointer in
net_dm_packet_report_size() if the reason is 0, as drop_reasons[0]
is NULL.

Fixes: 1330b6ef33 ("skb: make drop reason booleanable")
