[RFC PATCH 1/8] kdumpctl: fix a bug in remove_cmdline_param()

[Xunlei Pang]

For the following scripts,
  cmdline="root=/dev/mapper/rhel-root rd.lvm.lv=rhel/root quiet"
  remove_cmdline_param $cmdline "root"

we will get the result "rd.lvm.lv=rhel/ quiet", after this patch
we can get the correct "rd.lvm.lv=rhel/root quiet".
