Dan Carpenter 9c6f19421c 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).
