[PATCH] EDAC/versalnet: release remoteproc reference in remove

[Guangshuo Li]

mc_probe() gets a remoteproc reference with rproc_get_by_phandle() and
stores it in priv->mcdi->r5_rproc after the remote processor has been
booted.

The probe error paths release that reference with rproc_put(), but the
remove path only shuts the remote processor down. This leaks the
remoteproc device and module references on every successful probe/remove
cycle.

Call rproc_put() in mc_remove() after rproc_shutdown().
