ice: stop calling pci_disable_device() as we use pcim
Our driver uses devres to manage resources, in particular we call
pcim_enable_device(), what also means we express the intent to get
automatic pci_disable_device() call at driver removal. Manual calls to
pci_disable_device() misuse the API.
Recent commit (see "Fixes" tag) has changed the removal action from
conditional (silent ignore of double call to pci_disable_device()) to
unconditional, but able to catch unwanted redundant calls; see cited
"Fixes" commit for details.
Since that, unloading the driver yields following warn+splat:
[70633.628490] ice 0000:af:00.7: disabling already-disabled device

Note that this is the only Intel ethernet driver that needs such fix.
