Paul Sokolovsky 4718dac560 net: net_pkt_append: Take into account MTU when adding data to a packet 
If we were asked to add 10KB to a packet, adding it won't help -
such packet won't be even sent by hardware on our side, and if
it is, it will be dropped by receiving side. So, make sure we
never add more data than MTU as set for the owning interface.
This actually gets a bit tricky, because we need also to account
for protocol header space. Typically, when net_pkt_append() is
called, protocol headers aren't even added to packet yet (they
are added in net_context_send() currently), so we have little
choice than to assume the standard header length, without any
extensions.
