WINED3D: Use GL_LIMITS(samplers) instead of GL_LIMITS(sampler_stages) in IWineD3DSurfaceImpl_UnlockRect

[H. Verbeet]

GL_LIMITS(samplers) is the amount of samplers the card supports,
GL_LIMITS(sampler_stages) is the amount of sampler stages we have for
use with SetSamplerStage(). In this case we want the amount of
samplers.

Changelog:
  - Use GL_LIMITS(samplers) instead of GL_LIMITS(sampler_stages) in
IWineD3DSurfaceImpl_UnlockRect
