net: stmmac: Prepare to add Split Header support
In order to add Split Header support, stmmac_rx() needs to take into
account that packet may be split accross multiple descriptors.
Refactor the logic of this function in order to support this scenario.
Changes from v2:
- Fixup if condition detection (Jakub)
- Don't stop NAPI with unfinished packet (Jakub)
- Use napi_alloc_skb() (Jakub)
