[PATCH] PCI Hotplug: Fix echoing 1 to power file of enabled slot problem with SHPC driver

Here is a patch to fix the problem of echoing 1 to "power" file
to enabled slot causing the slot to power down, and echoing 0
to disabled slot causing shpchp_disabled_slot() to be called
twice. This problem was reported by kenji Kaneshige.

Thanks,
Dely
