scd:openpgp: Avoid PIN caching issues after re-select.

Browse Source 
* scd/app-openpgp.c (do_reselect): Clear PIN cache flags.
--

It seems that the verification status of the OpenPGP app on a Yubikey
is reset on a select.  We need to reflect this in our cache to avoid a
"Bad PIN" error on computing a signature.
