From: Ira Weiny <ira.we...@intel.com>
ib_find_send_mad only needs access to the MAD header not the full IB MAD.
Change the local variable to ib_mad_hdr and change the corresponding cast.
This allows for clean usage of this function with both IB and OPA MADs because
OPA MADs carry the same header as IB MADs.

Changes from V1
Make ib_mad_hdr const so as to not cast away the const of the WC
parameter.
