IB/mlx5: Fix use of null pointer PD

When a Raw Ethernet QP is created, a NULL pointer PD could be used.
Fixing that by only using the PD after validating it's valid.
smatch also reported this error:
drivers/infiniband/hw/mlx5/qp.c:1629 mlx5_ib_create_qp()
	 error: we previously assumed 'pd' could be null (see line 1616)

Fixes: 0fb2ed66a14c ('IB/mlx5: Add create and destroy functionality for Raw Packet QP')
