Subject[PATCH] PCI: endpoint: Fix clearing start entry in configfs
Date
The value of 'start' entry is no change whenever writing 0 to configfs.
So the endpoint that stopped once can't restart.

Fixes: d74679911610 ("PCI: endpoint: Introduce configfs entry for configuring EP functions")

Since the possibility of restarting endpoint is up to each controller,
if restart is prohibited on purpose for some reason, this patch can be
ignored.
