IB/hfi1: Correct oversized ring allocation

Browse source 
[ Upstream commit b536d4b2a2 ]

The completion ring for tx is using the wrong size to size the ring,
oversizing the ring by two orders of magniture.

Correct the allocation size and use kcalloc_node() to allocate the ring.
Fix mistaken GFP defines in similar allocations.
