perf record: Fix failed memory allocation for get_cpuid_str
In x86 architecture dependend part function get_cpuid_str() mallocs a
128 byte buffer, but does not check if the memory allocation succeeded
or not.
When the memory allocation fails, function __get_cpuid() is called with
first parameter being a NULL pointer. However this function references
its first parameter and operates on a NULL pointer which might cause
core dumps.
