Test files created by test_create*() tests will stay in the $efivarfs_mount directory unless the system was rebooted.
When the tester tries to run this efivarfs test again on the same system, the immutable characteristics in that directory will cause some "Operation not permitted" noises and a false-positve test result to the test_create_read() test.

Also, use this function to replace the existing file removal code.

Thanks for the patch. There is another patch that does the same in linux-kselftest next branch.
Please check to see if that fixes the problem you are seeing.
thanks, -- Shuah
