core/cgroup: drop extraneous CGRuntime check in unit_get_memory_available()

Currently, for units whose CGRuntime is not allocated just yet, e.g.
inactive ones, MemoryAvailable fails to account for their MemoryMax/High
settings. Let's remove the CGRuntime check hence. The call to
unit_get_memory_accounting() would certainly fail, but it doesn't matter,
since 'current' is initially set to 0 anyways.
