DAP server: buffer_full() not correct

[rgrr]

Hello

I'ld say that buffer_full() needs also the modulo operation for rptr, so that it reads

bool buffer_full(buffer_t *buffer)
{
	return ((buffer->wptr + 1) % DAP_PACKET_COUNT == buffer->rptr % DAP_PACKET_COUNT);
}

instead of

bool buffer_full(buffer_t *buffer)
{
	return ((buffer->wptr + 1) % DAP_PACKET_COUNT == buffer->rptr);
}
