pci: allow multiple calls to pcim_enable_device()
There's no reason not to allow multiple calls to pcim_enable_device().
Calls after the first one can simply be noop. All PCI resources will
be released when the initial pcim_enable_device() resource is
released.
This allows more flexibility to managed PCI users.
