simplify pnp_activate_dev() and pnp_disable_dev() return values
Make pnp_activate_dev() and pnp_disable_dev() return only 0 (success) or a
negative error value, as pci_enable_device() and pci_disable_device() do.
Previously they returned:
0: device was already active (or disabled)
1: we just activated (or disabled) device
<0: -EBUSY or error from pnp_start_dev() (or pnp_stop_dev())
Now we return only 0 (device is active or disabled) or <0 (error).
All in-tree callers either ignore the return values or check only for
errors (negative values).
