QCosmeticStroker: fix out-of-bounds access in drawPixel()
Found by UBSan:
src/gui/painting/qcosmeticstroker.cpp:150:55: runtime error: index -1 out of bounds for type 'QT_FT_Span_ [255]'
src/gui/painting/qcosmeticstroker.cpp:150:99: runtime error: index -1 out of bounds for type 'QT_FT_Span_ [255]'
src/gui/painting/qcosmeticstroker.cpp:151:55: runtime error: index -1 out of bounds for type 'QT_FT_Span_ [255]'
That code path makes no sense if no span has been populated
yet, so skip the whole block if current_span == 0.
