embedded: fix vc_translate operator precedence

This fixes a bug in operator precedence in the newly introduced vc_translate
macro. Without this fix, the translation of some characters on the
kernel console is garbled.

This patch was copied to the e-mail list previously for testing. Now,
all reports confirm that it works, so this is an official post for
application.
