drivers/video/exynos/exynos_mipi_dsi.c: fix an error check condition
Checking an unsigned variable for negative value returns false. Hence use the macro to fix it. Fixes the following smatch warning: drivers/video/exynos/exynos_mipi_dsi.c:417 exynos_mipi_dsi_probe() warn: unsigned 'dsim->irq' is never less than zero.
