[PATCH] lib/bitmap.c: add some check to correct the parse result

Sometimes the input from user may cause an unexpected result. for example, echo "1-3," > /proc/irq//smp_affinity_list. The correct result should be 1-3, however we got 0-4. To avoid this issue, we check if there is a ready digit. If no valid digit is set, we just continue to the next parse. Sig
