d3d9:visual - test_uninitialized_varyings() fails on w11pro64-amd:

visual.c:23014: Test failed: Got unexpected color 0x00000000, case 3.
visual.c:23014: Test failed: Got unexpected color 0x00000000, case 6.

These failures are systematic and only happen on w11pro64-amd (AMD RX 6600). In
particular they do not happen on fgtb-w10pro64-rx550 the only other test
machine to have an AMD GPU, nor do they happen on the other Windows 11 test
machines (w11pro64 and w11pro64-nv).
