Previously we handled the case when the installed kernel version for early kdump is different from dracut target, it will be better to print a warning even if installation successed, to let the user know that an different kernel is used. No warn message will be given if the user specified a KDUMP_KERNELVER value, as in such case a different kernel version is used on purpose.
