From: wang di <[email protected]> Remove fld lookup during configuration, so to avoid accessing FLDB on MDT0 before MDT0 is setup.
1. add od_is_ost to check whether the FID is on OST, instead of lookup in FLDB. 2. add oic_device in OI cache, so in OI cache lookup, it will try to match device to avoid the ino of agent inode is being retrieved from OI cache. Then osd_remote_fid, which will trigger fld lookup, can be removed from osd index lookup.
