PATCH 1/1 opensm/osm_vl15intf.c: Fix transaction ID printing in vl15_send_mad

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.

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

Right, this one is much better :)

This variable would make any sense only in case when appropriate log level is set. I think the better way to solve it is to revert the original patch and to print transaction id inside osm_vendor_send() (there is an error message anyway) before madw is freed.
