Simplify some code in CGdiDisplayDriver.

- GDI_StretchBitMask(), which is not an override, has a flags parameter
  that is never used. Remove it.
- StretchDIBits() checks its flags parameter and does an early return,
  but still continue to use it afterwards when its only possible value
  is 0. Replace the flags variable with 0.
