Subject: [PATCH 4.4 155/192] nvme: Call pci_disable_device on the error path.

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Gabriel Krisman Bertazi <krisman@...ux.vnet.ibm.com>


Commit 5706aca74fe4 ("NVMe: Don't unmap controller registers on reset"),
which backported b00a726a9fd8 to the 4.4.y kernel introduced a
regression in which it didn't call pci_disable_device in the error path
of nvme_pci_enable.
