ref-manual: Update SERIAL_CONSOLES_CHECK description

The previous description was not accurate. Looking at the code,
SERIAL_CONSOLES_CHECK does not act like SERIAL_CONSOLES, as it
will not add consoles to enable but only check and disable
consoles defined by SERIAL_CONSOLES. Also, the previous patch
adds aliasing functionality that needed to be documented.

I (Scott Rifenbark) did a bit of word-smithing here from the
original patch.
