RDMA/core: Reduce poll batch for direct cq polling



Fix warning limit for kernel stack consumption:

drivers/infiniband/core/cq.c: In function 'ib_process_cq_direct':
drivers/infiniband/core/cq.c:78:1: error: the frame size of 1032 bytes
is larger than 1024 bytes [-Werror=frame-larger-than=]

Using smaller ib_wc array on the stack brings us comfortably below that
limit again.

Fixes: 246d8b18 ("IB/cq: Don't force IB_POLL_DIRECT poll context for ib_process_cq_direct")
