[PATCH 1/1] video: exynos_mipi_dsi: 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.
