Franck Bui de2edc008a udev: bump TasksMax to inifinity (#3593)
udevd already limits its number of workers/children: the max number is actually
twice the number of CPUs the system is using.

(The limit can also be raised with udev.children-max= kernel command line
option BTW).

On some servers, this limit can easily exceed the maximum number of tasks that
systemd put on all services, which is 512 by default.

Since udevd has already its limitation logic, simply disable the static
limitation done by TasksMax.
