[ Upstream commit 3637a29ccbb6461b7268c5c5db525935d510afc6 ]
As comment of pci_get_domain_bus_and_slot() says, it returns a pci device with refcount increment, when finish using it, the caller must decrement the reference count by calling pci_dev_put(). Call pci_dev_put() before returning from bnx2x_vf_is_pcie_pending() to avoid refcount leak.
