\version "2.15.20"

\relative c'
{
  \key c \major
  \time 2/4
  c2 ~
  \cadenzaOn
  c4 \teeny d8-[ es f g-] \normalsize a4-\fermata
  \cadenzaOff
  \bar "|"
  \once\accidentalStyle forget
  e2 % how to suppress accidental cancellation here?
}

Note the version number.  \once worked for complex stuff with 2.15.17,
and the \accidentalStyle syntax comes with 2.15.20.  There will be
solutions for versions earlier than that, but I don't care getting
myself educated about them.

The real fix would be to mess with the Timing in a way that the \bar "|"
is not necessary.  One way is to switch the cadenza off one note early
and let the last note take a full measure:

\relative c'
{
  \key c \major
  \time 2/4
  c2 ~
  \cadenzaOn c4 \teeny d8-[ es f g-]
  \cadenzaOff \normalsize a4*2-\fermata
  e2 % how to suppress accidental cancellation here?
}
