LU-1198 idl: move FID VER to DLM resource name[1]

Until Lustre 1.8.7/2.1.1 the FID version was packed into name[2].

However, this leaves very little room in the LDLM resource name
for other uses.  The upcoming quota code needs to store another
FID into the LDLM resource to allow directory tree quotas, and
managed by the DLM.

The 32-bit VER, which is currently always 0, is moved into the high
bits of name[1] along with the 32-bit OID, to avoid consuming the
name[2] field.  Since future use of the FID version (including
snapshots, pools, etc) will need changes on the client side anyway,
there will never be non-zero VER on an existing client.
