[PATCH] mlx4_core: request MSIX vectors as much as there CPU cores

[Eli Cohen <eli-VPRAkNaXOzVS1MOuV/RT9w@public.gmane.org>]

The current code requires num_possible_cpus() + 1 MSIX vectors. However,
num_possible_cpus() stands for the max number of supported CPUs by the kernel.
We should use num_online_cpus() which is the number of available CPUs for the
system.
