MC: remove use of unnecessary variable

Due to the fact that the windows unwinding has the concept of chained frames, we
maintain a current frame info pointer that is adjusted on any push and pop of a
unwinding context.  This just removes an unnecessary variable that was used to
mirror the DWARF unwinding code.
