In 'struct ofpbuf' the 'frame' pointer was used to parse different kinds of
data (Ethernet, OpenFlow, Netlink attributes). For Ethernet packets the
'frame' pointer was supposed to have the same value as the 'data'
pointer.
Since 'struct dp_packet' is only used for Ethernet packets, there's no
need for a separate 'frame' pointer: we can use the 'data' pointer
instead.

The 'list' member is only used (two users) in the slow path.
This commit removes it to reduce the struct size

Currently dp-packet make use of ofpbuf for managing packet
buffers. That complicates ofpbuf, by making dp-packet
independent of ofpbuf both libraries can be optimized for
their own use case.
This avoids mapping operation between ofpbuf and dp_packet
in datapath upcalls.

dp_packet is short and better name for datapath packet
structure.
