Running the import more than once shouldn't matter, but it's a bit confusing and causes a slowdown too. This patch reworks the rules to avoid duplicted runs, but tries to keep the same imports. (E.g. import for pci devices without MODALIAS is only done for tty devices.) Note that this is only about hwdb import with argument, which uses MODALIAS as the lookup key. There are other imports done with different lookup keys.
