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

visual.c:24213: Test failed: Got unexpected color 0x00000000, case 1.

See https://test.winehq.org/data/patterns.html#d3d9:visual

This failure is systematic and only happens on w11pro64-amd (AMD RX 6600). In
particular it does not happen on fgtb-w10pro64-rx550 the only other test
machine to have an AMD GPU, nor does it happen on the other Windows 11 test
machines (w11pro64 and w11pro64-nv).
