Without this fix, remote feature request from host may not

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.

The old footer was appended after PDU using pointer arithmetic. Now
the footer fields have been moved to the header struct, the
footer fields are now statically located in the data structure,
this is type safe and fields can be referred to by their actual

thus avoiding pointer arithmetic. Secondly, this change will pave
