This looks like a valid fix to me.  Can you open a pull request on github with this fix, so we can get a commit message and signed-off-by line?

On a related note, the code that vrb_create_ep() is calling (vrb_get_rdma_rai) doesn't look right to me, or has another memory leak.  I will look into that and cleanup that code.
