drivers/video/exynos/exynos_mipi_dsi.c: fix an error check condition

Browse Source 
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.
