[LTP] [PATCH] runpwtests03:skip read check for the files without read permission

[shuang.qiu@oracle.com]

From: Shuang Qiu <shuang.qiu@oracle.com>

According to the cpufreq-stats doc,cpufreq/stats/reset is
write-only attribute of cpu freq sysfs file.
So skip the cat checking for the files like this file which
has not read permission.
