[Intel-wired-lan] [PATCH] fm10k: restore D0 power state upon probe

[Jacob Keller]

It seems that under some circumstances, such as after performing an
unbind following an AER injection recovery, the power state of a VF
isn't set to PCI_D0. Following the unbind if we attempt to bind the
device, the MSI-X initialization fails due to incorrect power state.

Fix this by always calling pci_set_power_state(pdev, PCI_D0) on driver
device probe.
