grDStyle.c: GrLoadStyles() scount, The left operand of '<' is a garbage value

The use of 'scount' in this function looks complex, it seems to be reset to
zero sometimes and incremented at others.  Analysis shows there is a possible
path where is maybe used uninitialized.

Setting to zero seems like a good choice.
