[PATCH] kdumpctl: skip the selinux-relabel of specifying mount info

[Pingfan Liu]

When user specifies nfs mount info like:
    path /
    core_collector makedumpfile -d 31
    dracut_args --mount "host:/path /var/crash nfs defaults"
kdump service neither guarantees the correctness, nor relabels it.
