RDMA/cxgb3: Don't exceed the max HW CQ depth
commit dc4e96ce2dceb649224ee84f83592aac8c54c9b7 upstream.
The max depth supported by T3 is 64K entries. This fixes a bug
introduced in commit 9918b28d ("RDMA/cxgb3: Increase the max CQ
depth") that causes stalls and possibly crashes in large MPI clusters.
