What yum command line did you use that gave the above errors?

I'm not an expert on yum, but the above errors seem to indicate that 3 
versions of chkconfig are involved: 1.7.2-1.el7_3.1, 1.7.2-1.el7 and 
1.3.61-4.el7 - not sure of the significance of this ...

I guess you could try removing ntsysv and then trying to update 
chkconfig and then re-install ntsysv :

  yum remove ntsysv
  yum update chkconfig
  yum install ntsysv
