[PATCH] nvme: Unmap CMB and remove sysfs file in reset path

[Stephen Bates]

> 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.

> Fixes: 202021c1a ("nvme : Add sysfs entry for NVMe CMBs when appropriate")
