nvmesensor: fix crash caused by passthruInterface during host reboot

During host power cycle or reboot, nvmesensor will crash due to the
exception `org.freedesktop.DBus.Error.FileExists: File exists` and
restart.

The original patch forgot to remove the passthruInterface in the
destructor function of NVMeControllerEnabled class. When device
warm-reboot, nvmesensor will delete and recreate NVMeControllerEnabled,
thus triggering this FileExists DBus error.

Tested:
Before the fix, nvmesensor will crash when `ipmitool chassis power cycle`
After the fix, nvmesensor doesn't crash when `ipmitool chassis power cycle`
