[th/device-release-ports] device: fix hanging port devices when controller goes down while port is not fully attached
This partly reverts 1fe8166f ('device: only deactivate when the master we've enslaved to goes away').
If the controller fails while the port is not yet fully attached, before this patch the following happened:
<info> [1664299566.1065] device (bond0): state change: ip-config -> failed (reason 'config-failed', sys-iface-state: 'managed')
...
<warn> [1664299566.1073] device (bond0): Activation: failed for connection 'bond0'
<trace> [1664299566.1073] device[6b76ac7314eb0b53] (bond0): master: release one slave a9f10ea824bb1725/eth1 (not enslaved) (configure)
<debug> [1664299566.1073] device[a9f10ea824bb1725] (eth1): unmanaged: flags set to [!sleeping,!by-type,!platform-init,!user-explicit,!user-settings,!user-conf=0x0/0x179/managed], forget [is-slave=0x800], reason removed)
...
<info> [1664299566.1080] device (eth1): state change: config -> ip-config (reason 'none', sys-iface-state: 'managed')
Note that now eth1 has no controller, but it lingers in "ip-config" state indefinitely.
If we look at a case where the port is already attached we see:

Fix that by not ignoring the nm_device_slave_notify_release() call. Now we get:

Commit 1fe8166f ('device: only deactivate when the master we've enslaved to goes away') added the "return", but it seems to also add it in cases where we need to handle this. Restrict the return to cases if we do "no-config".
