[Mesa-dev] [PATCHv2 2/4] nvc0: Silence uninitialized variable warning in the release build

[Emil Velikov]

Resolves the following gcc warning

 warning: 'ptr' may be used uninitialized in this function
    xy[0] = ptr[sample_index][0] * 0.0625f;
               ^

v2: Bail out when using non-conformant sample_count (spotted by calim)
