PCI/PM: Make power management op coding style consistent
Some of the power management ops use this style:
struct device_driver *drv = dev->driver;
if (drv && drv->pm && drv->pm->prepare(dev))
drv->pm->prepare(dev);
while others use this:
const struct dev_pm_ops *pm = dev->driver ? dev->driver->pm : NULL;
if (pm && pm->runtime_resume)
pm->runtime_resume(dev);
Convert the first style to the second so they're all consistent. Remove
local "error" variables when unnecessary. No functional change intended.
