Kairui Song 94a7b43407 Always drop nofail or nobootwait options
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.

# KDUMP_COMMANDLINE="ro root=LABEL=/"

# root= options are copied from /proc/cmdline. In general it is best to append
