Don't re-query inventory when trimming failed/dark hosts

Since the filter list contains hosts, passing that back to list_hosts()
in the inventoy causes issues when the hostname is an IPv6 address
(with :'s interpreted as group unions). Since we already have the list
of hosts, we should not need to pass that back through inventory a
second time.

Fixes #7446
