Data transmission was paused when PHY update request control
PDU was enqueued in ULL. If there was pending data PDU in
ULL that was not enqueued towards LLL, this caused
transmission to stall.
Move the tx pause due to PHY update request/response being
enqueued to pre_tx_ack callback, this way all pending PDUs
in ULL is enqueued to LLL.

If LL Connection Parameter Request or LL Connection Update
or LL PHY Update procedure is started by the local device
while a LL Length Update Request PDU has been sent by peer
then a Rx node has been stored in the llcp_rx place holder
for generation of Length Update procedure complete.
The failing assert check is incorrect in the above scenario
hence remove. Instead a missing append of the allocated Rx
node to the llcp_rx list has been added to the controller
implementation.

Fix for possible Tx Buffer leak during disconnection when
the buffers are in ULL context and not yet enqueued towards
LLL context.
Signed-off-by: Vinayak Kariappa Chettimada <vich@nordicsemi.no>
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.
