drm: simpledrm: fix a potential NULL dereference
The drm_format_info() function returns NULL if the format is
unsupported, but the simplefb_get_validated_format() is expected to
return error pointers. If we propagate the NULL return then it will
lead to a NULL dereference in the callers. Swap the NULL and trade it
in for an ERR_PTR(-EINVAL).
