Title: Fix badarg issue on module update web site

This commit fixes the following error, triggered by accessing the `Nodes` → `$node` → `Update` page of the web interface:

bad argument in call to erlang:iolist_to_binary(ok) in ejabberd_web_admin:get_node/5

The `Check` variable always holds an atom (`ok` or `error`).
