Use translated error messages in PortaudioBackend when SR or i/o channel counts don't match requested

These errors are probably preventable but currently they do occur so at least
tell the user about them(and hope they check the error log window)

Use debug output rather than sending errors for developer relevant port errors
...
Most of these are not errors that are intended for the user, they are only
intended for developers so don't send them to PBD::error. The errors that may
be relevant to users should be handled in libardour or the GUI in response to
return values
