atm: fore200e: Fix build warning.
GCC (rightfully) complains that:
drivers/atm/fore200e.c:614:5: warning: operation on 'cmdq->head' may be undefined
This is due to the FORE200E_NEXT_ENTRY macro, which essentially
evaluates to:
i = ++i % m
Make it what's explicitly intended here which is:
i = (i + 1) % m
and the warning goes away.
