If nofail or nobootwait option is used, systemd's local-fs.target won't wait for the mounting to complete, and kdump might start before the required mount point is ready and then fail. The host might use nofail for reasons like the device may get unpluged, and if the device is not mounted and it is set as kdump target as the same time then kdump service won't start, we will never enter the capture kernel. By the time we have entered the capture kernel, the target device must exist and ready to use, or else kdump would fail anyway. So force remove nofail and nobootwait option. Also drop rootflags=nofail option, as we don't depend on rootfs anymore if the dump target don't required it. So the nofail option is no longer needed.
