sd-dhcp6-client: drop unnecessary event_source_disable()
...
The event source will be soon re-enabled in the same function.
The function client_timeout_resend() may return earlier without
re-enabling the timer souce. However,
- the timer event source is one shot by default. Hence, it is not
necessary to disable in the callback function,
- when it returns early, then client_set_state() or client_stop() is
called before return, and they re-ernable or disable the timer.

The timer must be active until the client get re-enter bound state,
and the timeout must be determined by the lease acquired when entering
the bound state.

enabled,

network: attempt to trigger kernel IPv6LL address generation
...
Try to ensure kernel IPv6 link local address generation occurs by
setting the per-if addr_gen_mode sysctl when the link is already up,
instead of the netlink interface (IFLA_INET6_ADDR_GEN_MODE).
The netlink setting is sufficient in cases where the interface is not
yet up when networkd configures an interface - bringing the interface
up will trigger in-kernel address generation.
If the interface is already up, yet the interface has no IPv6LL assigned
setting IFLA_INET6_ADDR_GEN_MODE has no effect.
Writing the addr_gen_mode sysctl is a best effort attempt at triggering
address generation regardless of interface state because it also works
in cases where the interface is already up.
Fixes #22424 .
