eCryptfs: Remove ECRYPTFS_NEW_FILE crypt stat flag
Now that grow_file() is not called in the ecryptfs_create() path, the ECRYPTFS_NEW_FILE flag is no longer needed. It helped ecryptfs_readpage() know not to decrypt zeroes that were read from the lower file in the grow_file() path. Signed-off-by: Tyler Hicks <tyhicks@linux.vnet.ibm.com>
