can: raw: raw_setsockopt: limit number of can_filter that can be set
commit 332b05ca7a438f857c61a3c21a88489a21532364 upstream.
This patch adds a check to limit the number of can_filters that can be
set via setsockopt on CAN_RAW sockets. Otherwise allocations > MAX_ORDER
are not prevented resulting in a warning.
