Fix ticker previous slot value with elapsed ticks value from
the time stopped ticker has expired. When a ticker is
stopped, if it was in its reserved time space, then the
currently occupied slot (was set to 0) should be the amount
of time that has elapsed in the expired and stopped ticker's
reserved time space and beyond until the stop.
This is required to ensure that any other new ticker does
not get scheduled over the stopped ticker's reserved time
space.
Fixes#19515.

When running a ticker node as "must expire", the node would invoke the
ticker callback even when programmed with latency. As "must expire" is
intended for scheduled events which are skipped due to collision, and as
such expected by LLL, purposefully skipped events should not generate
"must expire" callbacks.

Fix for possible Tx Buffer leak during disconnection when

LLL context.

When more than one simultaneous connections are active,
transmitting data packets to peer, a termination causes
host to use the flushed pending number of completed packets
count for other active connections. This is on reception
of HCI disconnection complete event. But the controller has
not yet released any of the pending enqueued Tx buffers
which was happening after the disconnection event was
dispatched to HCI layer.
The fix here is to dispatch the disconnection complete event
from the LLL context after pending Tx buffers have been
flushed and the buffers get returned to Tx pool in the ULL
context. This way buffers are in the Tx pool before host
get to process the disconnection complete event.

Fix issue in the handling of LL_REJECT_EXT_IND packets, this would look

When multiple simultaneous peripheral connections are
supported, restarting connectable advertising by host on
peripheral connection establishment failed in controller.
This prevented establishing new connections while first
connection was active.
The failure was caused by a bug in the way controller was
using quota for Rx PDU buffers. As the quota count was
release before the connection complete event rx PDU buffer
being released, the Rx PDUs needed to reserve for
connection complete event for new connectable advertising
was not available. This caused the connectable advertising
