Added a support to set cpu affinity mask for each MSIX vector enabled by the HBA. So that, running the irqbalancer will balance interrupts among the cpus. Change_set: 1. Added affinity_hint varable of type cpumask_var_t in adapter_reply_queue structure. And allocated a memory for this varable by calling alloc_cpumask_var. 2. Call the API irq_set_affinity_hint for each MSIx vector to affiniate it with calculated cpus at driver inilization time. 3. While freeing the MSIX vector, call this same API to release the cpu affinity mask for each MSIx vector by providing the NULL value in cpumask argument. 4. then call the free_cpumask_var API to free the memory allocated in step 2.
