vfio: selftests: Eliminate overly chatty logging

Eliminate overly chatty logs that are printed during almost every test.
These logs are adding more noise than value. If a test cares about this
information it can log it itself. This is especially true as the VFIO
selftests gains support for multiple devices in a single test (which
multiplies all these logs).
