console: Fix LOG_FAST macro

In the LOG_FAST macro, the comparison was incorrectly made with 'level'
value. Correct is the comparison with 'speed'.
With the wrong comparison you cannot set a lower level for console log,
the highest level is always output.

TEST:
- Boot mc_ehl2 with console log level 5 and check output
