Subject: [PATCH 4.14 05/29] IB/qib: Fix memory leak in qib_user_sdma_queue_pkts()

From: José Expósito <jose.exposito89@...il.com>

[ Upstream commit bee90911e0138c76ee67458ac0d58b38a3190f65 ]

The wrong goto label was used for the error case and missed cleanup of the
pkt allocation.

Fixes: d39bf40e55e6 ("IB/qib: Protect from buffer overflow in struct qib_user_sdma_pkt fields")
