Subject: sunrpc: fix expiry of auth creds

sunrpc: fix expiry of auth creds

commit f1bafa7375c01ff71fb7cb97c06caadfcfe815f3 upstream.

Before this commit, with a large enough LRU of expired items (100), the
loop skipped all the expired items and was entirely ineffectual in
trimming the LRU list.

Fixes: 95cd623250ad ('SUNRPC: Clean up the AUTH cache code')
