PCI: hv: Only queue new work items in hv_pci_devices_present() if necessary

If there is pending work in hv_pci_devices_present() we just need to add
the new dr entry into the dr_list. Add a check to detect pending work
items and update the code to skip queuing work if pending work items
are detected.
