eCryptfs: Remove ecryptfs_header_cache_2
Now that ecryptfs_lookup_interpose() is no longer using ecryptfs_header_cache_2 to read in metadata, the kmem_cache can be removed and the ecryptfs_header_cache_1 kmem_cache can be renamed to ecryptfs_header_cache. Signed-off-by: Tyler Hicks <tyhicks@linux.vnet.ibm.com>
