eCryptfs: Remove ecryptfs_unlink_sigs warnings

A feature was added to the eCryptfs umount helper to automatically unlink the keys used for an eCryptfs mount from the kernel keyring upon umount. This patch keeps the unrecognized mount option warnings for ecryptfs_unlink_sigs out of the logs. Signed-off-by: Tyler Hicks <tyhicks@linux.vnet.ibm.com>
