PCI: PM: Do not call platform_pci_power_manageable() unnecessarily
Drop two invocations of platform_pci_power_manageable() that are not necessary, because the functions called when it returns 'true' do the requisite "power manageable" checks themselves. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Tested-by: Ferry Toth <fntoth@gmail.com>
