[PATCH v2 7/8] bootstrap_read_devfs(): Remove all partitions upon function completion

[Andrey Smirnov]

Bootstrap_read_devfs does not remove the devices it creates during the
course of its execution which might be considered as a resource
leak. Remedy that by adding the code to remove those devices upon
function completion.
