IB/mlx4: Fix memory leaks

[ Upstream commit 5c1baaa82cea2c815a5180ded402a7cd455d1810 ]

In mlx4_ib_alloc_pv_bufs(), 'tun_qp->tx_ring' is allocated through
kcalloc(). However, it is not always deallocated in the following execution
if an error occurs, leading to memory leaks. To fix this issue, free
'tun_qp->tx_ring' whenever an error occurs.
