fix parse_affinity for CPU numbers greater than 31
The function parse_affinity reports wrong results for CPU numbers
greater than 31.
The problem is caused by the function bitmastlist which parse_affinity
calls. The fix treats the inpput line as a long hexbitmask instead of an
array in order to produce correct results
