Remove log translation related check

Since we're preparing to remove log translation from project, we
should remove translation check to ensure tests pass.

For log translation removal, see link [1][2].

LOG Translations
----------------
LOG.debug messages will not get translated. Use ``_LI()`` for
``LOG.info``, ``_LW`` for ``LOG.warning``, ``_LE`` for ``LOG.error``
and ``LOG.exception``, and ``_LC()`` for ``LOG.critical``.
``_()`` is preferred for any user facing message, even if it is also
going to a log file. This ensures that the translated version of the
message will be available to the user.
The log marker functions (``_LI()``, ``_LW()``, ``_LE()``, and ``_LC()``)
must only be used when the message is only sent directly to the log.
Anytime that the message will be passed outside of the current context
(for example as part of an exception) the ``_()`` marker function
must be used.
A common pattern is to define a single message object and use it more
than once, for the log call and the exception. In that case, ``_()``
must be used because the message is going to appear in an exception that
may be presented to the user.
