Error message

Description of problem:
If a update gives an error while downloading, he update process stops

Version-Release number of selected component (if applicable):
yum-3.4.3-125.el7.noarch

How reproducible:
Every time a download of a RPM package for updates is not successful you get the attached error. The solution is quite simple. In the case of the screenshot, a simple removing of the RPM from the yum cache folder solves the issue (rm -f /var/cache/yum/x86_64/7Workstation/production-rhel-x86_64-workstation-7/packages/mesa-dri-drivers-10.2.7-5.20140910.el7_1.1.x86_64.rpm) and run yum update again

Actual results:
if the checksum of the file does not fir the expected result, you get the attached error message.

Expected results:
yum should at least once try to remove the rpm completely and download it again
