debian: patches: Fix mismatch between number of samples

After updating Mesa to 25.2.0 (Debian experimental) Chromium is now causing panfrost errors:

[  717.324402] panfrost 13000000.gpu: js fault, js=0,
                   status=JOB_BUS_FAULT, head=0xc22ad00, tail=0xc22ad00

After bisecting, the problematic commit is 423f3fd4850 ("panfrost: enable 8x and 16x msaa modes when supported").

The root cause appears to be a mismatch between the number of samples in the depth and color buffers. This commit adds a possible fix, as proposed by Eric Smith.
