eCryptfs: ecryptfs_keyring_auth_tok_for_sig() bug fix
The pointer '(*auth_tok_key)' is set to NULL in case request_key() fails, in order to prevent its use by functions calling ecryptfs_keyring_auth_tok_for_sig(). Signed-off-by: Roberto Sassu <roberto.sassu@polito.it> Cc: <stable@kernel.org> Signed-off-by: Tyler Hicks <tyhicks@linux.vnet.ibm.com>
