dracut-kdump.sh: recursively umount fs and its submounts

Browse Source 
Certain dracut module will mount fs under real root(/sysroot/ or
$NEWROOT/). Thus root fs can not be umounted by `umount /sysroot/`.

We should use `umount -R /sysroot/` to recursively umount root and
its submounts.

v2: do the same for dump_fs() from Baoquan
