net: remove comments that mention obsolete __SLOW_DOWN_IO

The only remaining definitions of __SLOW_DOWN_IO (for alpha and ia64) do
nothing, and the only mentions in networking are in comments.  Remove these
mentions.

made udelay() unreliable.
The old method of using an ISA access as a delay, __SLOW_DOWN_IO__, is
deprecated.
