No reassembly logic is changed besides removing the final reassembled
pointer. Instead of requiring such pointer, let's just use the frag one.
Such changes will ease the usage of ieee802154_reassemble():
the given frag buffer, in case it finally got reassembled and thus
provided a NET_CONTINUE verdict, will directly be handled by net_core.
This makes things consistent as well with verdicts:
- in case of NET_OK, buf has been consumed and thus unrefed
- in case of NET_DROP, buf needs to be unrefed by caller
- in case of NET_CONTINUE, buf is updated with reassembled and
decompressed data packet, up to net_core to handel it accordingly.

As soon as fragment is put into the cache and as long as it is not
identified to be the last one: let's return NET_OK to notifiy the
fragment has been consumed by ieee802154 L2.
That way, net_core will not try to interpret it - and fail - unnecessary
increasing the drop statistics.
On the contrary, once the buffer is fully reassemble, let's return
NET_CONTINUE in order to let net_core consume the buffer relevantly.

We would be using STXON, since FRMCTRL1_SET_RXENMASK_ON_TX bit is set,
behavior would be the same.
Recalibrating the RX will uselessly abort any received frames before TX
or right after RX got reinstated. So, let's not do that and trust that

This relies on net_context_get_ip_proto() providing the correct
protocol given a certain context. Currently, it only returns either
TCP or UDP, which is sufficient for net_ipv6_create(). However, enum
net_ip_protocol contains other unhandled protocols (ICMP and ICMPv6,
respectively), which might or might not need to be handled in the
future.

This change is related to patch called
"net: Adapt to new behavior of net_buf_frag_add"
This version removes extra net_nbuf_unref() from
the code. The unref was done because net_buf_frag_del()
did not remove the double ref from the list element.
Because of the other patch, the list does not have
double ref any more, so we need to remove the extra
unref in couple of extra places.
