[PATCH] pinentry_setbufferlen returns pin when already large enough

[Daniel Kahn Gillmor]

* pinentry/pinentry.c (pinentry_setbufferlen): when pin buffer is
  already large enough, return the buffer instead of NULL.
  pinentry-curses.c is the only place that checks this return value
  now, and it expects this behavior.
