drm/exynos: g2d: make ioctls more robust
Both exynos_g2d_set_cmdlist_ioctl and exynos_g2d_exec_ioctl don't check
if the G2D was succesfully probe. If that is not the case, then g2d_priv
is just NULL and extracting 'dev' from it in the next step is going to
produce a kernel oops.
Add proper checks and return ENODEV if the G2D is not available.
