[PATCH 2/2] selftests: x86: vdso_restorer: Return correct exit statuses

[Muhammad Usama Anjum <usama.anjum@xxxxxxxxxxxxx>]

Return correct exit status, KSFT_SKIP if the pre-conditions aren't met.
Return KSFT_FAIL if error occurs. Use ksft_finished() which will
compmare the total planned tests with passed tests to return the exit
value.
