drm/fb_helper: Fix potential NULL pointer dereference
kcalloc returns NULL on failure. Hence check for the return value
and exit on error to avoid NULL pointer dereference.
Fixes the following smatch errors:
drivers/gpu/drm/drm_fb_helper.c:1271 drm_setup_crtcs() error:
potential null dereference 'modes'. (kcalloc returns null)
drivers/gpu/drm/drm_fb_helper.c:1272 drm_setup_crtcs() error:
potential null dereference 'crtcs'. (kcalloc returns null)
