acquire_home() takes a reference to a sd-bus object, which the open_session hook cleans on success. But only when handling a user actually owned by homed, it did not clean it up when skipping because it is being invoked on a system user. We need to be careful with sd-bus here as pam_sm_open_session is the last hook before forking, and we want to clean up sd-bus before that happens, or we'll have a broken reference (FDs are cloexec) in the child process, which will then assert when attempting to close them, or leak the bus connection which causes dbus to complain loudly: dbus-daemon[62]: [system] Connection has not authenticated soon enough, closing it (auth_timeout=30000ms, elapsed: 30020ms) (cherry picked from commit db0c0f5e003b0a0e202dbc399d35db36087c641c) (cherry picked from commit 0045d952b5db4b8761892faef2a2e173111c6333)
