  Log Message:
  -----------
  fixed memory leak

fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=32324

sc_enum_apps() causes card->cache.current_ef to be allocated for
IAS/ECC, but not freed if any other error occurs during initialization.
since sc_enum_apps() is called anyway during PKCS#15 initialization.
Having this at the card driver level (instead of the PKCS#15 level) is
not needed.
