[PATCH 06/12] staging: lustre: fid: add a connect flag for open by FID

[James Simmons]

From: Lai Siyao 

Add OBD_CONNECT_OPEN_BY_FID for open by FID, if MDS supports this,
for open by FID, it won't retry with name if object with the FID
doesn't exist; while if client supports this, client won't pack
name in open request if FID is known.
