IB/hfi1: Initialize bth1 in 16B rc ack builder
[ Upstream commit 8935780b9f7bbad0f2eb5dd43f61ba7b509a1575 ]
It is possible the bth1 variable could be used uninitialized so going
ahead and giving it a default value.
Otherwise we leak stack memory to the network.
Fixes: 5b6cabb0db77 ("IB/hfi1: Add 16B RC/UC support")
