[SCSI] fcoe: Use per-CPU kernel function for dev_stats instead of an array
Remove the hotplug creation of dev_stats, we allocate for all possible CPUs
now when we allocate the lport.
v2: Durring the 2.6.30 merge window, before these patches were comitted,
'percpu_ptr' was renamed 'per_cpu_ptr'. This latest update updates this
patch for the name change.
