cluster/dht: force set dir inode ctx cached time in setattr()

In setattr, the inode times may have been explicitly set "back
in time". In such cases, if the inode ctx times are not force
set, then they continue to be higher and continue serving the
higher/older value in future calls to dht_inode_ctx_time_update()
