bug in intelfbhw.c

Hello,

we would like to use your drivers in our software. While debugging we
found a bug in calculating the ring_space.
If there is less then RING_MIN_FREE available in the ring buffer,
dinfo->ring_space is set to a big value forcing wait_ring to return.
We have attached a possible solution to solve this bug.
