RDMA/core: Reduce poll batch for direct cq polling
[ Upstream commit d3b9e8ad425cfd5b9116732e057f1b48e4d3bcb8 ]
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: 246d8b184c10 ("IB/cq: Don't force IB_POLL_DIRECT poll context for ib_process_cq_direct")
