netvsc: optimize receive path
Do manual optimizations of receive path:
- remove checks for impossible conditions (but keep checks
for bad data from host)
- pass argument down, rather than having callee recompute what
is already known
- remove indirection about receive buffer datalength
- remove dependence on VLAN_TAG_PRESENCE
- use _hot/_cold and likely/unlikely
