hw/block/nvme: fix invalid msix exclusive uninit

Commit 1901b4967c3f changed the nvme device from using a bar exclusive
for MSI-x to sharing it on bar0.

Unfortunately, the msix_uninit_exclusive_bar() call remains in
nvme_exit() which causes havoc when the device is removed with, say,
device_del. Fix this.

Additionally, a subregion is added but it is not removed on exit which
causes a reference to linger and the drive to never be unlocked.
