tcp: bump max rcv buffer size for autoscalingHEADmain

This allows in higher throughput values with default settings.
In the review I was proposing using 16 MB, but in the transport
call today we settled on a more conservative value of 8.
Bumping it further will be done in combination with mitigations
for mbuf exhaustion attacks.
