driver core: return an error when dev_set_name() hasn't happened

The commit d21fdd07cea4 ("driver core: Return proper error code when
dev_set_name() fails") rewrote the logic of handling the dev_set_name()
error codes, but missed the point that initially set error value to
-EINVAL might be rewritten and hence the error path can't be triggered
at some circumstances. To fix this, make sure that error variable is
set to -EINVAL when other conditionals are false.
