ofed_scripts/utils/mlnx_tune: Fix CPU detection

When a device local NUMA node is not detected, mlnx_tune still tries to initialize a local CPU list. Fixed two issues: 1. When querying for the CPU list and getting a range, the last core is excluded. 2. On some cases the CPU list has duplications. Verified on a VM with no NUMA detection.
