Are you doing \once \override or just \override?  A singular \override 
will affect all Hairpins from that point in the music forward (or until 
another \override or a \revert).  Assuming you want this behavior for 
all Hairpins across all staves, just do the \override at a suitably 
global level.

%%%%
% Top-level or within \score
\layout { \context { \Staff \override Hairpin.to-barline = ##f } }
%%%%

If you need to scope this to a particular Staff, either use the \with 
block or just \override as the first thing in the music:

%%%%
\new Staff \with { \override Hairpin.to-barline = ##f } { ... }
% or %
{ \override Hairpin.to-barline = ##f ... }
%%%%

Finally, if you need a mixture of Hairpins that either extend to the 
note or stop at the barline, then you might want to define a helper 
variable:

%%%%
extend = -\tweak to-barline ##f \etc

\fixed c' { \time 3/4 g2 a8 \extend \< b | \time 2/4 cis'2 \! }
%%%%
