(get_cached_data): New arg GET_IMMEDIATE to bypass

Browse source 
the cache.  Changed all callers.
(get_one_do): Bypass the cache if the value would have been read
directly for v1.1 cards.It makes things a bit slower but obnly for
1.0 cards and there are not that many cards out in the wild.  This
is required to fix a caching bug when generating new keys; as a
side effect of the retrieval of the the C4 DO from the 6E DO the
chaced fingerprint will get updated to the old value and later
when signing the generated key the checking of the fingerprint
fails becuase it won't match the new one.  Thanks to Moritz for
analyzing this problem.
(verify_chv3): Removed the CHV status reread logic because we
won't cache the C4 DO anymore.
