Kairui Song 539bff4083 Append both nofail and x-systemd.before to kdump mount target 
By this point, there is still an unresolved vfs kernel issue that blocks
systemd from mounting the dump target properly from time to time. To
prevent systemd from failing by mounting the dump target, we can add
nofail option to the kdump mount point.

But adding nofail will wipe out default dependency of the mount point,
see commit 94a7b43, so systemd randomize the order of calling kdump.sh
and mounting the dump target and lead to unexpected behavior.
However we can use x-systemd.before to ensure the mount is done
in right order.

In dracut-kdump-capture.service, we have "After=initrd.target",
and look at dracut.bootup.7, systems start processing of fstab by
initrd-fs.target, so set "After=initrd.target" could ensure the mount
is ready before pre-pivot and kdump-capture service.

Now with both nofail and x-systemd.before=initrd.target, systemd
will try to mount the dump target before calling kdump, and even if the
mount failed, kdump.sh will still be called and try to mount again. See
dump_fs function, which will try to mount if the target is not mounted.
Kdump will only fail if both mount attemp fails.

Else if the kdump target mount failed or unstable, systemd will directly
jump to kdump failure action, and kdump fails.

This should improve the robustness in general with no other risk.
