scsi: smartpqi: Add sysfs entry for NUMA node in /sys/block/sdX/device

Browse source 
Although NUMA node is a PCIe device level attribute, it was requested the
NUMA node be added for each exposed device similar to NVMe disks.

Example for NVMe:

  /sys/block/nvme1c1n1/device/numa_node

Example for smartpqi:

  /sys/block/sdh/device/numa_node

  cat /sys/block/sdh/device/numa_node
