[PATCH] mkdumprd: display the absolute path of dump location in the check_user_configured_target()

[Lianbo Jiang]

When kdump service fails, the current errors do not display the
absolute path of dump location(marked it as "^"), for example:

kdump: kexec: unloaded kdump kernel
kdump: Stopping kdump: [OK]
kdump: Detected change(s) in the following file(s):  /etc/kdump.conf
kdump: Rebuilding /boot/initramfs-4.18.0-304.el8.x86_64kdump.img
kdump: Dump path "/var1/crash" does not exist in dump target
"UUID=c202ef45-3ac3-4adb-85e7-307a916757f0"
                  ^^^^^^^^^^^
kdump: mkdumprd: failed to make kdump initrd
kdump: Starting kdump: [FAILED]

Here, it should output the absolute path of dump location with this
format: "<mount path>/<path>". To fix it, let's extend the
relative
pathname to the absolute pathname in check_user_configured_target().
