kernfs: Rearrange kernfs_node fields to reduce its size on 64bit

Browse source

Moving .flags and .mode right below .hash makes kernfs_node smaller by 8
bytes on 64bit. To avoid creating a hole from 8 bytes alignment on 32bit
archs, .priv is moved below so that there are two 32bit pointers after the
64bit .id field.

v2: Updated to avoid size increase on 32bit noticed by Geert.
