when idp is enabled, always daemon(up2k-rescan)

fixes a bug reported on discord;

1. run with `--idp-h-usr=iu -v=srv::A`
2. upload a file with up2k; this succeeds
3. announce an idp user: `curl -Hiu:a 127.1:3923`
4. upload another file; fails with "fs-reload"

the idp announce would `up2k.reload` which raises the
`reload_flag` and `rescan_cond`, but there is nothing
listening on `rescan_cond` because `have_e2d` was false

must assume e2d if idp is enabled, because `have_e2d` will
only be true if there are non-idp volumes with e2d enabled
