IB/mlx4: Fix memory leak if QP creation failed

Browse Source 
commit 5b420d9cf7 upstream.

When RC, UC, or RAW QPs are created, a qp object is allocated (kzalloc).
If at a later point (in procedure create_qp_common) the qp creation fails,
this qp object must be freed.

Fixes: 1ffeb2eb8b ("IB/mlx4: SR-IOV IB context objects and proxy/tunnel SQP support")
