lib.sh: remove erroneous break from fx_

it means nothing here. in context, if a non-zero return
is observed, we should not do anything here, which is
already the behaviour anyway, except that "break" means
nothing since we're not in a loop here.

where an error exit should be observed, x_ is used inside
the command given for fx_
