Subject: [PATCH] media: solo6x10: increase FRAME_BUF_SIZE

In practice, devices sometimes return frames larger than current buffer
size, leading to failure in solo_send_desc().
It is not clear which minimal increase in buffer size would be enough,
so this patch doubles it, this should be safely assumed as sufficient.
