PCI: pciehp: Leave power indicator on when enabling already-enabled slot
If an error occurs when enabling a slot, pciehp_power_thread() turns off the power indicator. But if the only error is that the slot was already enabled, we should leave the power indicator on. Return success if called to enable an already-enabled slot. This is in the same spirit of the special handling for EEXISTS when pciehp_configure_device() determines the slot devices already exist.
