staging: lustre: clio: update file attributes after sync

Browse Source 
This really only affects clients that are attached to lustre
server running ZFS, because zfs does not update # of blocks
until the blocks are flushed to disk.

This patch update file's blocks attribute after OST_SYNC completes.
