tcp: fix signed/unsigned comparison
Kernel test robot reported:
smatch warnings:
net/ipv4/tcp_input.c:5966 tcp_rcv_established() warn: unsigned 'reason' is never less than zero.
I actually had one packetdrill failing because of this bug,
and was about to send the fix :)
v2: Andreas Schwab also pointed out that @reason needs to be negated
before we reach tcp_drop_reason()
Fixes: 4b506af9c5b8 ("tcp: add two drop reasons for tcp_ack()")
