Beat Küng d1fcd39a44 fix crsf_rc: prevent potential buffer overflow for unknown packets
The length check for unknown packets did not include PACKET_SIZE_TYPE_SIZE
and CRC_SIZE, and hence working_index could overflow CRSF_MAX_PACKET_LEN,
triggering invalid memory access further down in QueueBuffer_PeekBuffer.

Also the working_segment_size was wrong for unknown packets.

Credits for finding this go to @Pwn9uin.
