From: Colin Ian King <colin.king@canonical.com>
The current allocation for dev->caps.spec_qps is for the size of the pointer and not the size of the actual mlx4_spec_qps structure. Fix this by using the correct size. Also splint allocation over a few lines to make it cppcheck clean on overly wide lines.
Detected by CoverityScan, CID#1455222 ("Wrong sizeof argument")
