We were using sys_slist_remove() to remove object, object instance and
observer w/o passing the previous sys_snode_t to it (NULL).
This will instruct the function to treat the node as the list head and
result in unexpected behavior after the removal.
Correct it by using sys_slist_find_and_remove() or passing the previous
node to the function.

When a request demands to create a new object instance, it will search
whether the request object instance exists or not. However, current
implementation does not reset the lwm2m_engine_obj_inst at the time it
is deleted. It only removes the object instance from the sys list.
Correct the behavior by resetting both object instance and resource
instances at the time it's deleted. Also, consolidate function
lwm2m_delete_handler() and lwm2m_delete_obj_inst().
To reproduce the issue, try to create light control object instance
(/3301), delete the created instance and create it again. You shall find
following error message dumped.
> [ipso_light_control] [ERR] light_control_create: Can not create
instance - already existing: 0
> [lib/lwm2m_engine] [ERR] lwm2m_create_obj_inst: unable to create obj -

prepare_arp() was unreferencing original pkt (called pending there) in
case of error.
net_prepare_arp() was always unreferencing pkt, though it could have
been already unreferenced by prepare_arp() as seen previously which is
an extra bogus unref in this case.
And in case it returned NULL, ethernet_send() would return NET_DROP
which in turn would make net_if's tx code to unref again the pkt.
This patch ensures pkt is unrefed only once and at the right place.

Fixes an assert during connection establishment when the
initiator overflows the initiator window in time while
sending the CONNECT_IND PDU. The actual window is one low
frequency tick less, hence corrected the check that permits
the transmission of CONNECT_IND PDU inside the initiator
window.
Symptom was, stopping of the scanner's ticker succeeds on
connection establishment, but next interval prepare was
already run when continuous scanning was used, breaking the
design, hence there was an assert.
