phosphor-hwmon: Udev rules should never block
If we create a dependency in the hwmon service that makes it take extra
time to start, this will block up all of udev and prevent other devices
from being discovered as we wait on the specific hwmon instance to
start. This can result in deadlocks.
Typical convention in udev is to block as little as possible to avoid
these type of scenarios. udev can't handle failures so it's pointless to
wait anyway. The service start will still be queued up as expected.
Tested:
Ran on a machine configured to use hwmon. Configured sensors can
still be read and the daemons start as expected.
