- re-arange the code to make static code analysis tool happy.
- If no valid conversion could be performed, a zero value is returned
(0L) from strtol(), so add a sanity check "isdigit(cp[0])" to ensure
that it won't unexpectedly parse CPU 0 if the string starts or ends
with the valid delimiters ',' or '-', for example:
-- cpu_affinity 1,
-- cpu_affinity ,1
