Upgrade various logging in the VFIO selftests drivers from dev_info() to dev_err(). All of these logs indicate scenarios that may be unexpected. For example, the logging during probing indicates matching devices but that aren't supported by the driver. And the memcpy errors can indicate a problem if the caller was not trying to do something like exercise I/O fault handling. Exercising I/O fault handling is certainly a valid thing to do, but the driver can't infer the caller's expectations, so better to just log with dev_err().
