driver core: let dev_set_drvdata return int instead of void as it can fail
Before commit
b402843 (Driver core: move dev_get/set_drvdata to drivers/base/dd.c)
calling dev_set_drvdata with dev=NULL was an unchecked error. After some
discussion about what to return in this case removing the check (and so
producing a null pointer exception) seems fine.
