[PATCH 1/5] wined3d: Set the read buffer to GL_NONE in surface_load_ds_location().

[Henri Verbeet]

On GL implementations that don't support GL_ARB_ES2_compatibility the
framebuffer's read buffer has to be valid, even if we're not reading from it.
This fixes a regression on r600g introduced by
dcc969c32ce479ddeed7277f04c18994a017dfb5.
