[CPUFREQ] drivers/cpufreq/cpufreq.c: Adjust error handling code involving cpufreq_cpu_put
After calling cpufreq_cpu_get, error handling code should call
cpufreq_cpu_put.
The semantic match that finds this problem is as follows:
(http://www.emn.fr/x-info/coccinelle/)
// <smpl>
@r@
expression x,E;
statement S;
position p1,p2,p3;
@@
(
if ((x = cpufreq_cpu_get@p1(...)) == NULL || ...) S

... when != x
if (x == NULL || ...) S

<...
if@p3 (...) { ... when != cpufreq_cpu_put(x)
when != if (x) { ... cpufreq_cpu_put(x); ...}

}
