[PATCH AUTOSEL 6.2 35/45] nvme-pci: fixing memory leak in probe teardown path

[Sasha Levin]

From: Irvin Cote <irvincoteg at gmail.com>

[ Upstream commit a61d265533b7fe0026a02a49916aa564ffe38e4c ]

In case the nvme_probe teardown path is triggered the ctrl ref count does
not reach 0 thus creating a memory leak upon failure of nvme_probe.
