libcacard/cac: Remove unused statement (value stored is never read)

Warning from ccc-analyzer:

libcacard/cac.c:192:13: warning: Value stored to 'ret' is never read
            ret = VCARD_DONE;
            ^     ~~~~~~~~~~

Here 'ret' is assigned a value inside of a switch statement and also after
that switch statement.
