ecryptfs: checking return code of ecryptfs_find_auth_tok_for_sig()

This patch replaces the check of the 'matching_auth_tok' pointer with
the exit status of ecryptfs_find_auth_tok_for_sig().
This avoids to use authentication tokens obtained through the function
ecryptfs_keyring_auth_tok_for_sig which are not valid.
