failed cell dependency check should not set invalid values (tdf#132451)

Calc's dependency check done before parallel formula cell group
calculation tries to ensure valid cell values for all the dependencies
of the group's cell, and if it detects a problem such as a cycle
it bails out. But since ScFormulaCell::Interpret() simply bailed out
without doing anything, other cells could use that cell's possibly
incorrect value for their calculation and get their dirty flag reset.

This fix adds a flag to mark that bailing out is in progress, which
ensures the bail-out is short-circuited and no cell values are set.
