[PATCH] kdumpctl: Export DUMP_TARGET

[Bhupesh Sharma]

When building kdump initramfs for a SSH dump target, mkdumprd would
check whether it has the write permission on the SSH Server's
$DUMP_TARGET.

However $DUMP_TARGET is missing in the actual error message when the
user doesn't not have the write permission. For example:

# kdumpctl restart
   kexec: unloaded kdump kernel
   Stopping kdump: [OK]
   Could not create temporary directory on :/home/bhsharma/test. Make
   sure user has write permission on destination
   mkdumprd: failed to make kdump initrd
   Starting kdump: [FAILED]

This patch exports $DUMP_TARGET from kdumpctl to make sure that
mkdumprd can use the same inside mkdir_save_path_ssh() function to
fix the issue. Note that without this patch, $DUMP_TARGET is
uninitialized in mkdumprd.
