conf: Remove do-nothing validation functions

There are three address validation routines that do nothing:
  virDomainDeviceDriveAddressIsValid()
  virDomainDeviceUSBAddressIsValid()
  virDomainDeviceVirtioSerialAddressIsValid()

Remove them, and replace their call sites with "1" which is what they
currently return. In some cases this means we can remove an entire
if block.
