tests/kms_psr2_su: Print errno while it fails to read debugfs
This tests is being sporadically skipped in CI as it is not due
"PSR sink not reliable: yes". This commit adds printing of debugfs
("tests/kms_psr2_su: Print debugfs when skipping test"), but it is not
enough to track error cases.
It adds printing of errorno while it fails to read debugfs.
