Certiain udev entries might be of a size that makes libudev emit EINVAL which right now leads to udevEventHandleThread exiting. Due to no more handling events other elements of libvirt will start pushing for events to be consumed which never happens causing a busy loop burning a cpu without any gain.
After evaluation of the root cause of the example case discussed in in #245 and a test run ignoring EINVAL it was considered safe to add EINVAL to the ignored errnos to not exit udevEventHandleThread giving it more resilience.
Fixes: #245
