this patch improves rpaphp_find_pci_dev. First it uses the for_each_pci_dev
macro instead of the while loop, making this hotplug safe (which is a good
idea in a hotplug driver, isn't it?). Then it removes retval_dev. retval_dev
is set to the found device when something is found, NULL otherwise. If
nothing is found dev will be NULL at the end of the loop anyway and the
found device if we found something, no need for retval_dev then. And a very
small coding style fix.
