fs/ecryptfs/: possible cleanups
- make the following needlessly global code static:
- crypto.c:ecryptfs_lower_offset_for_extent()
- crypto.c:key_tfm_list
- crypto.c:key_tfm_list_mutex
- inode.c:ecryptfs_getxattr()
- main.c:ecryptfs_init_persistent_file()
- remove the no longer used mmap.c:ecryptfs_lower_page_cache
- #if 0 the unused read_write.c:ecryptfs_read()
