ipmi: Remove unnecessary pci_disable_device.

[Dave Jones]

We call cleanup_one_si from ipmi_pci_remove, which calls ->addr_source_cleanup,
 which gets set to point to ipmi_pci_cleanup, which does a pci_disable_device.

On return from this, we do a second pci_disable_device, which
results in the trace below.
