Subject: nvme: unmap CMB and remove sysfs file in reset path

From: Jon Derrick <[email protected]>

commit f63572dff1421b6ca6abce71d46e03411e605c94 upstream.

CMB doesn't get unmapped until removal while getting remapped on every reset. Add the unmapping and sysfs file removal to the reset path in nvme_pci_disable to match the mapping path in nvme_pci_enable.
