[Devel] [PATCH vz10 v2] selftests/tdx: skip when the TDX guest device is absent

[Konstantin Khorenko]

From: Eva Kurchatova <eva.kurchatova@virtuozzo.com>

verify_report fails outside a TDX guest, where /dev/tdx_guest does not
exist.

Skip only when the device node is missing, so that a real open()
failure, EPERM or EBUSY, still fails the test instead of being
reported as a skip.

Changes in v2:
- skip only when the device node itself is missing (errno == ENOENT).
  v1 skipped on any open() failure, so a real problem such as EPERM or
  EBUSY was reported as a skip instead of a failure.  As a side effect
  the following ASSERT_LT() is reachable again and no longer dead code.
- commit message: explain why the skip is narrowed to a missing node.
