net/mlx5: Fix setting number of EQs of SFs
[ Upstream commit f88c4876347400a577598e06f1b230a7b19ee0e9 ]
When setting number of completion EQs of the SF, consider number of
online CPUs.
Without this consideration, when number of online cpus are less than 8,
unnecessary 8 completion EQs are allocated.
