[PATCH] mkdumprd fail if target is NFS and mounted on /var/crash

Now when dump target is not specified, separate disk can't be mounted on
"path", e.g /var/crash. However if target is specified, whatever the default
fail action is set, mkdumprd should go ahead and not be failed.
In check_block_dump_target(), the check only on disk is not complete,
NFS and ssh need be filtered too. So introduce is_user_configured_dump_target
to check this.
