If, in ib_link_query_port(), the call to mlx4_MAD_IFC() fails we will
currently do 'return err;' which will leak 'in_mad' and 'out_mad' that
we previously allocated. I believe we should instead do 'goto out;'
where we'll properly free the memory we previously allocated.

thanks, applied (looks like a 3.4 regression so I'll send the fix to
Linus with my next batch)

not sure to follow on the next branch part, it is a regression
introduced in 3.4-rc1 so it should be in your fixes branch
and submitted within a batch possibly containing more fixes, isn't that?
