The NFS_INO_REVAL_FORCED flag needs to be set if we just got a delegation, and we see that there might still be some ambiguity as to whether or not our attribute or data cache are valid. In practice, this means that a call to nfs_check_inode_attributes() will have noticed a discrepancy between cached attributes and measured ones, so let's move the setting of NFS_INO_REVAL_FORCED to there.
