Andriy Gapon f92e3400bc remove process and jail directory machinations from dounmount ...

The manipulations done by mountcheckdirs() are not that useful during
the unmount, they can bring about unexpected security consequences.

Thic change effectively reverts the change in r73241.

The change also allows to simplify the handling of rootvnode global
variable.
