device: Avoid calling unit_free(NULL) in device setup logic (#4748)
Since a581e45ae8f9bb5c, there's a few function calls to unit_new_for_name which will unit_free on failure. Prior to this commit, a failure would result in calling unit_free with a NULL unit, and hit an assertion failure, seen at least via device_setup_unit: Assertion 'u' failed at src/core/unit.c:519, function unit_free(). Aborting. Fixes #4747 https://bugs.archlinux.org/task/51950
