Marcin Gasiorek fb99f65fe9 net: ip: Fix for improper offset return by net_pkt_find_offset() 
The original packet's link-layer destination and source address can be
stored in separately allocated memory. This allocated memory can be
placed just after pkt data buffers.
In case when `net_pkt_find_offset()` uses condition:
`if (buf->data <= ptr && ptr <= (buf->data + buf->len)) {`
the offset is set outside the packet's buffer and the function returns
incorrect offset instead of error code.
Finally the offset is used to set ll address in cloned packet, and
this can have unexpected behavior (e.g. crash when cursor will be set
to empty memory).
