From: Mustafa Ismail <mustafa.ismail@xxxxxxxxx>
If i40iw_allocate_dma_mem fails when creating a QP, the
memory allocated for the QP structure using kzalloc is not
freed because iwqp->allocated_buffer is used to free the
memory and it is not setup until later. Fix this by setting
iwqp->allocated_buffer before allocating the dma memory.
Fixes: d37498417947 ("i40iw: add files for iwarp interface")
