SUNRPC: Make the credential cache hashtable size configurable
This patch allows the user to configure the credential cache hashtable size using a new module parameter: auth_hashtable_size When set, this parameter will be rounded up to the nearest power of two, with a maximum allowed value of 1024 elements.
