RDMA/mlx5: Fix prefetch memory leak if get_prefetchable_mr fails

Browse source

destroy_prefetch_work() must always be called if the work is not going
to be queued. The num_sge also should have been set to i, not i-1
which avoids the condition where it shouldn't have been called in the
first place.
