[ Upstream commit 8f4ab7da904ab7027ccd43ddb4f0094e932a5877 ]
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.
Fixes: ebd5858c904b ("selftests/powerpc: Add test for all DSCR sysfs interfaces")
