util: fix inspect indentation of detached DataView

formatExtraProperties() raised ctx.indentationLvl before reading the
property. The getters of a detached DataView throw, so the level was
never lowered again, and the DataView and everything inspected after it
in the same call ended up indented too far. Read the value first.
