ieee802154: 6lowpan: remove full-size calculation workarounds

Hi,

this patch series based on "ieee802154: 6lowpan: separate receive/transmit functionality".

In this patch series I mainly removes the lowpan_uncompress_size function workarounds. Why this is a workaround solution? So this function parse again the 6LoWPAN header for getting the 6LoWPAN header size. We do parsing twice and this is the first ugly thing there. The second thing is that when we add new header compression we need to touch the lowpan_uncompress_size again for adding next header size calculation. This series removes the workaround so we need to parse/create this only once. It was myself which introduce this workaround to have at first something which works. Since Martin Townsend work which put out the lowpan_give_upper_layer outside of the iphc decompression we can handle it now in that way.

This patch also includes some cleanup patches which I detect while programming this one. In futher the 6LoWPAN parsing should look like mac802154 parsing. mac802154 parsing look like mac80211. To rework the 6LoWPAN parsing will be the next steps.
