> 
> The QP setup function allocates buffer for its opaque MR and register it into
> MR structure.
> 
> After buffer alloction and before MR registration, it tries allocate MR Btree.
> When the MR Btree allocation fails, the buffer was not freed what caused a
> memory leak.
> 
> Allocate the MR Btree before buffer alloction.
