Bug 2257563

When "inxi -C" or any usage of inxi that includes the Cpu information is used on a system where hyperthreads are turned off by setting /sys/devices/system/cpu/smt/control to "off", the cpu information for those hyperthread cores show up as uninitialized values for those cores (example is a quad core Skylake):

$ inxi -C
Use of uninitialized value $value[0] in string ne at /usr/bin/inxi line 9857.
Use of uninitialized value $value[0] in string ne at /usr/bin/inxi line 9857.
Use of uninitialized value $value[0] in string ne at /usr/bin/inxi line 9857.
Use of uninitialized value $value[0] in string ne at /usr/bin/inxi line 9857.
CPU:
  Info: quad core model: Intel Core i7-6700HQ bits: 64 type: MCP cache:
    L2: 1024 KiB
  Speed (MHz): avg: 835 min/max: 800/3500 cores: 1: 800 2: 800 3: 862 4: 880

Expected result:  inxi -C should show those as "offline" or at least not the uninit errors

Reproducible: Always

Steps to Reproduce:
1.Turn off hyperthreads by echoing "off" into /sys/devices/system/cpu/smt/control
2.Run "inxi -C"

Actual Results:  
Output listing contains a "Use of uninitialized value $value[0] in string ne at /usr/bin/inxi line 9857."  for each HT core that was set to offline, for a 4 core cpu this is seen:

inxi -C
Use of uninitialized value $value[0] in string ne at /usr/bin/inxi line 9857.
Use of uninitialized value $value[0] in string ne at /usr/bin/inxi line 9857.
