The vhost_scsi VHOST_NEW_WORKER requires the inherit_owner

In the error recovery path of mlx5_vdpa_dev_add(), the cleanup is
executed and at the end put_device() is called which ends up calling

Replace direct error handling with 'ksft_test_result_*',
'ksft_print_msg' and KSFT_SKIP macros for better reporting.
Test logs:
Before change:
- Without root
error: unshare, errno 1
- With root
No, output
After change:
- Without root
TAP version 13
1..1
ok 1 # SKIP This test needs root
This version 4 patch series replace direct error handling methods with ksft
macros, which provide better reporting.Currently, when the tmpfs test runs,
it does not display any output if it passes,and if it fails
(particularly when not run as root),it simply exits without any warning or
message.

Add skip test if not run as root, with an appropriate Warning.
Add 'ksft_print_header()' and 'ksft_set_plan()' to structure test
outputs more effectively.

Use 0 for the values as we use them for the return value on init
to keep the test modules simple. This fixes a splat reported
do_init_module: 'test_kallsyms_b'->init suspiciously returned 255, it should
follow 0/-E convention
