lib: Adjust the log levels in ux_locales.c

The function ux_locales_get_text() should expect to have a correct
preram_locales region to read, hence we need to adjust the log levels
inside lib/ux_locales.c:ux_locales_get_text():
* If the region does not exist or is not in a correct format, we should
  print in BIOS_ERR
* If the arguments are not correct but we have a good workaround (e.g.
  the lang_id from vboot API seems weird), we should print in
  BIOS_WARNING.

Also change some minor syntax issues.
