For some unknown reason, yres_virtual was 2x larger the the size specified by i915 and so when blit_clear_margins() tried to clear the full virtual right-hand margin it tried to write far beyond the end of the buffer. This limits the clear to only the visible portion of the right-hand margin, similar to how the bottom margin is treated.
