Skip expired keys when iterating a KEYRING ccache
In krcc_next_cred(), if keyctl_read_alloc() fails with EKEYEXPIRED,
skip it and move on to the next key in the keyring. This can happen
if a credential in the cache expires before the whole cache expires,
because for a period of time after a key expires, the key still exists
in the keyring but cannot be accessed. Reported by Ao Shen.
