selftests/powerpc: Fix resource leaks

Browse source 
In check_all_cpu_dscr_defaults, opendir() opens the directory stream.
Add missing closedir() in the error path to release it.

In check_cpu_dscr_default, open() creates an open file descriptor.
Add missing close() in the error path to release it.
