opensm/osm_vl15intf.c: Fix transaction ID printing in vl15_send_mad

Rather than reverting commit 546399c3b983cdfe7adf4bd0b179358744603478,
another alternative is to save off the transaction ID prior to
sending the MAD.

Right, this one is much better :)

This resolves OpenSM crash when accessing fields of mad that has already
been returned to the pool.
