IB/mad: Add final OPA MAD processing
For devices which support OPA MADs
1) Use previously defined SMP support functions.
2) Pass correct base version to ib_create_send_mad when processing OPA MADs.
3) Process out_mad_key_index returned by agents for a response. This is
necessary because OPA SMP packets must carry a valid pkey.
4) Carry the correct segment size (OPA vs IBTA) of RMPP messages within
ib_mad_recv_wc.
5) Handle variable length OPA MADs by:
* Adjusting the 'fake' WC for locally routed SMP's to represent the
proper incoming byte_len
* out_mad_size is used from the local HCA agents
1) when sending agent responses on the wire
2) when passing responses through the local_completions
function
NOTE: wc.byte_len includes the GRH length and therefore is different
from the in_mad_size specified to the local HCA agents.
out_mad_size should _not_ include the GRH length as it is added
